<h3>Answer:</h3>

d. The y-intercept is 1 space higher.
a. 9 to the power of -1/2

<h3>Step-by-step explanation:</h3>

1. Changing f(x) to f(x) + 1 adds 1 to every output value of the function, moving that value "1 space higher". This is true for the y-intercept, too.

___

2. The rules of exponents apply:

a^b · a^c = a^(b+c)
1/a^b = a^-b

You apparently want to simplify ...

... 9^(1/4) × 9^(1/2) / 9^(5/4)

... = 9^(1/4 + 1/2 - 5/4)

... = 9^((1+2-5)/4)

... = 9^(-2/4) = 9^(-1/2)

21=-b \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\times (-1) \\
\boxed{b=-21}$

The value of b is -21.
