First plug in (x+h) for x in the function.
f(x+h)= 2(x-h)^2-3(x-h) = 2(x^2-2xh+h^2)-3x-3h =
2x^2-4xh+2h^2-3x-3h - 2x^2 +3x =
(-4xh +2h^2-3h)/h
-4x +2h-3

Distance is the formula :
D

=
so

= 13
Answer is C)
we are given
y varies directly with x
so, we can write equation as

where
k is a constant
now, we need to find k
we are given
y=3 when x=8
so, we can plug it and find k


now, we can plug it back

(A)
we have got equation as

for finding inverse , we can switch x and y

now, we can solve for y


............Answer
(B)
we have

we can plug x=4 and find y

Answer:
9
Step-by-step explanation:
f(2), if f(x)=(x+1)^2
x=2
(2+1)^2
3^2=3x3
=9
