Step-by-step explanation:

<u>How to find the inverse of a function.</u>

- Replace f(x) with y

- Swap x and y places. (sign doesn't matter here.)

- solve for y.

f(x) = 8√x

y = 8√x

x = 8√y

x^2 = (8√y)^2

x^2 = 64y

y = x^2 / 64

= (1/64) x^2

Explain how to solve 4^(x + 3) = 7 using the change of base formula log base b of y equals log y over log b. In your answer, inc

valkas [14]

Answer:

-1.596

Step-by-step explanation:

4^(x + 3) = 7

log₄ 4^(x + 3) = log₄ 7

x + 3 = log₄ 7

x + 3 = log 7 / log 4

x = -3 + log 7 / log 4

x ≈ -1.596

Answer:

$y = \frac{1}{8}(x + 4)^2 + 4$

Step-by-step explanation:

Given:

Focus of parabola: (-4, 6)

Directrix: y = 2

Required:

Equation for the parabola

<h2><u>SOLUTION:</u></h2>

Using the formula, $y = \frac{1}{2(b - k)}(x - a)^2 + \frac{1}{2}(b + k)$ , the equation for the parabola can be derived.

Where,

a = -4

b = 6

k = 2

Plug these values into the equation formula

$y = \frac{1}{2(6 - 2)}(x - (-4))^2 + \frac{1}{2}(6 + 2)$

$y = \frac{1}{2(4)}(x + 4)^2 + \frac{1}{2}(8)$

$y = \frac{1}{8}(x + 4)^2 + \frac{8}{2}$

$y = \frac{1}{8}(x + 4)^2 + 4$
