Can someone explain this to me??
SOVA2 [1]

Answer:

Yes. g⁻¹(x) = f(x).

Step-by-step explanation:

Let y = ∛x - 1.

Rearrange to solve for x:

y+1 = ∛x

(y+1)³ = x

Swap x and y:

(x+3)³ = y

g⁻¹(x) = (x+3)³ = f(x)

Y=8x-4 find y and x intercept
dlinn [17]

Answer:

<h3>The x intercept is 1/2</h3><h3>The y intercept is - 4</h3>

Step-by-step explanation:

y = 8x - 4

First to find the y intercept let x = 0

Substitute the value of x into the equation

That's

y = 8(0) - 4

y = - 4

<h3>The y intercept is - 4</h3>

To find the x intercept let y = 0

Substitute the value of y into the equation

that's

8x - 4 = 0

8x = 4

Divide both sides by 8

x = 1/2

<h3>The x intercept is 1/2</h3>

Hope this helps you
