F(x) = 2x^2 - 3x, calculate f(x+h)-f(x) / h
kvasek [131]
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

Suppose that y varies directly with x, and y=3 when x=8
spayn [35]

we are given

y varies directly with x

so, we can write equation as

y=kx

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

3=k*8

k=\frac{3}{8}

now, we can plug it back

y=\frac{3}{8}x

(A)

we have got equation as

y=\frac{3}{8}x

for finding inverse , we can switch x and y

x=\frac{3}{8}y

now, we can solve for y

8*x=8*\frac{3}{8}y

8*x=3y

f^{-1}(x)=\frac{8x}{3}............Answer

(B)

we have

y=\frac{3}{8}x

we can plug x=4 and find y

y=\frac{3}{8}*4

y=\frac{3}{2}................Answer
