Choose the correct expressions using the fewest number of bases possible that are equivalent to the current expression. Select A

<h3>2 Answers: Choice B, Choice C</h3>

The rule we use here is $\frac{a^b}{a^c} = a^{b-c}$

If the font size is too small, then it says (a^b)/(a^c) = a^(b-c)

We subtract the exponents when dividing exponentials like this. The bases must be the same.

So this means the exponents 13 and 3 subtract to get 13-3 = 10

We either have an exponent of "13-3" or an exponent of "10" as an equivalent expression. The base stays at 2 the entire time.

If g(x)is the inverse of f(x) and f (x) = 4 x + 12, what ig(x)

Fynjy0 [20]

Answer:

The inverse of a given function

d) $g(x) = \frac{1}{4} x - 3$

Step-by-step explanation:

Explanation:-

Given that f(x) = 4x + 12

let y = 4 x + 12

4 x = y - 12

$x = \frac{y-12}{4}$

$x = \frac{1}{4} y - 3$

we know that y = f(x)

⇒ x = f⁻¹(y)

$(f^{-1} y) = \frac{1}{4} y - 3$

Put replace 'y' in 'x'

$(f^{-1} x) = \frac{1}{4} x - 3$

Final answer:-

The inverse of a given function

$g(x) = \frac{1}{4} x - 3$
