Answer:

  increase by 15

Step-by-step explanation:

We know the rate of change of h(x) is given by the coefficient of x, -5/7. This means any change in x will be reflected as a change in h(x) by -5/7 times the amount of the change.

Here, we're talking about a change in x of -21, so the change in h(x) will be ...

  (-5/7)·(-21) = 5·(21/7) = 15

The positive sign means the value of h(x) will increase by 15.

<h3>What is a fraction?</h3>

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

3^{-2}

= 1/3²

3² = 3 X 3 = 9

= 1/9

4^{-3}

= 1/4³

4³ = 4 x 4 x 4 = 64

= 1/64

2^{-6}

= 1/2^{6}

2^{6} = 2 x 2 x 2 x 2 x 2 x 2 = 64

= 1/64

Thus.,

The exact value in fractions are:

a) 1/9

b) 1/64

c) 1/64
