The answer for this problem is C. 20
Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.
Answer:
Proved!
Step-by-step explanation:
For two functions f(x) and g(x) to be inverses of each other then;
f(g(x)) = x and g(f(x)) = x condition must be satisfied.
<u>Checking: A. f(x) = 7x³ + 10 and g(x) = ∛</u><u />
<u />
So f(g(x)) = 7()³ + 10
We get; 7() + 10 = x - 10 + 10 = x (*<em>This is correct!)</em>
<em />
So g(f(x)) =
Ten cancels out and we are left with;
= = x (* <em>This is also correct!)</em>
