Answer:
Step-by-step explanation:
All three functions in the figure are parabolic and thus share the parent function . They are horizontally dilated by some constant (unless they aren't) and can all be represented with
, where
is some constant.
Plug in point the line passes through to find that constant. For , we can see the function clearly passes through (2,4):
Therefore, the function of is
Answer:
The area in factored form is .
The area in standard form is .
Step-by-step explanation:
The area of a rectangle is length times width.
So the area here is (x+2)(x-5).
They are probably not looking for A=(x+2)(x-5) because it requires too little work.
They probably want A in standard form instead of factored form.
Let's use foil:
First x(x)=x^2
Outer: x(-5)=-5x
Inner: 2(x)=2x
Last: 2(-5)=-10
---------------------Adding together: .
The area in factored form is .
The area in standard form is .
