The domain and scope of the identity function are the same. Equation for the identity function is f(x) = x, or y = x.
What is function?An statement, rule, or law in mathematics that specifies the connection between an independent variable and a dependent variable (the dependent variable). A relationship between a group of inputs and one output each is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. Y=X2 is an illustration of this. You only receive one output for y if you enter anything for x. The fact that x is the input value leads us to argue that y is a function of x.

x-3=4
x= ______
explain
Answer:
7
Step-by-step explanation:
In order to solve the value of x we need to Seperate it so that it can be alone on one side.
So:
X - 3 = 4
X = 4+3 (when characters go from one side of the "=" to the other, they change the sign that is before them (so if before the "=" it was "-" now it will be "+". Same goes for when we multiply or divide))
X=7
Answer:
X=7 because
-3=3=0,
and 4+3= 7 so x= 7

A circular plate has a diameter of 9 inches. What is the area of the plate? Explain the steps you follow to get to your answer
Answer:
The area of the circular plate is: " 63.59 in² " .
______________________________________________________
Note:
______________________________________________
diameter, "d" = 9 in. (given).
radius, "r" = "d/ 2 " = "(9 inches) / 2 " = 4.5 in.
______________________________________________
Area of a circle, "A" :
A = * r² ;
in which: "A = Area of circle ("plate"); in units of "square inches"; or "in² " ;
" = 3.14 " {approximation we shall use} ;
"r = radius = 4.5 in." ;
________________________________________________________
Plug in our known values to solve for the area, "A" :
A = (3.14) * (4.5 in)² ;
A = (3.14) * (4.5)² * (in²) ;
A = (3.14) * (4.5) * (4.5) * (in²) ;
A = 63.585 in² ; round to: " 63.59 in² " .

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-4,-6). What is the vertex of the function defined as
g(x) = f(x) + 3?
Answer:
(- 4, - 3 )
Step-by-step explanation:
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
For
g(x) = f(x) + 3
This is the graph of f(x) shifted 3 units up
Given the vertex of f(x) = (- 4, - 6 ), then
vertex of g(x) = (- 4, - 6 + 3) = (- 4, - 3 )

Step-by-step explanation:
i did this
The true statement is (d) m<S = m<P
How to determine the true statement?When a figure is rotated, the side lengths and the angle measures of the figure remain unchanged.
This means that:
The figure RST is congruent to the figure OPQ.
The choice of option that supports the above highlight is
m<S = m<P
Hence, the true statement is (d) m<S = m<P

What is the solution to this using substitution method pls show ur work
Answer:
x=-6, y=0
Step-by-step explanation:
Use the 3x-9y=-18 equation and add 9y to both sides to have 3x on its own on the left side. Then, divide by 3 on both sides. Then you'll have x=-6+3y. Plus this back into the 5x+4y=-30 equation and you'll get 5(-6+3y)+4y=-30. Use the distributive property and you'll get -30+15y+4y=-30. Simplify and get -30+19y=-30, then add 30 to both sides and you'll get 19y=0. Divide by 19 on both sides and you'll get y=0. Now that we know y=0, plug that back into the 5x+4y=-30 equation, and you'll get 5x+4(0)=-30. Simplify and you'll get 5x=-30. Divide by 5 on both sides and you'll get x=-6.
