Answer:

0

(1/3)x+13/3

5

Step-by-step explanation:

1. Like any function, <em>g</em> takes numbers from it's domain (-8, -3, 0, 7), and transforms them into numbers in it's range (8, 6, -3, 3). <em>g</em>^-1, it's inverse, maps back from the range into the domain. Since <em>g</em> maps 0 onto -3, g^-1 must turn -3 back to 0

g(0)=-3 == g`(-3)=0

2. To find the inverse of <em>h</em>, let h(x)=y.

Now, <em>y</em><em>=</em><em>3</em><em>x</em><em>-</em><em>1</em><em>3</em>

Remember that the inverse maps from the range (the y values) back to the domain (the x's), We want the function that takes a <em>y</em> and turns it into an <em>x</em><em>.</em><em> </em>For this, we must solve for x.

From above, <em>y</em><em>/</em><em>3</em><em>+</em><em>1</em><em>3</em><em>/</em><em>3</em><em>=</em><em>x</em>

Now that we rearranged <em>h</em>, we must flip the x and y to get the inverse. This happens because the range of <em>h</em> acts as the domain for <em>h</em><em>^</em>-1

3. The function <em>h</em> will turn 5 to some unknown number. Let's call it w. Then, if you pass w to h^-1, it will be turned back to a 5.

This is equivalent to computing the functions in the reverse order, or writing the composite, which results in x=y, and then computing

MrMuchimi
3(2x+8)=8x+46
6x+24=8x+46
-2x+24=46
-2x=22
x=-11

3(2(-11)+8)=8(-11)+46
3(-22+8)=-88+46
3(-14)=-42
-42=-42
