Answer:

1st option

Step-by-step explanation:

let y = f(x) and rearrange making x the subject

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

$\frac{y-1}{2}$ = x

Change y back into terms of x with x being the inverse h(x)

h(x) = $\frac{x-1}{2}$ = $\frac{1}{2}$ x - $\frac{1}{2}$

sq in.
Explanation:
V
=
s
3

64
=
s
3

find the cubic root of each side
3
√
64
=
s

4
=
s

so the side of the cube is 4 cu in.
The surface area of a cube is

S
A
=
n
A

where
S
A
is surface area,
n
is the number of faces, and
A
is the area of one face.
Te area of one face (
A
) is
s
2

so
A
=
16

n

S
A
