<span>Your equation is:
f(x) = 7x - 2
Solve for x.
Add 2 to both sides of this equation to get:
f(x) + 2 = 7x
Divide both sides of this equation by 7 to get:
(f(x) + 2)/7 = x
Since, in general, a = b implies that b = a, this equation becomes:
x = (f(x) + 2)/7
Replace x with f(x) and replace f(x) with x to get:
f(x) = (x+2)/7
That's your inverse function.
Graph both your function and your inverse function.
Set y = f(x) to get:
y = 7x - 2 (your regular function).
y = (x+2)/7 (your inverse function).
Graph also the function y = x.

Hi there!
The answer is C.
She should use the mode to describe the data obtained from the survey. The mode includes listing the count of all of the different topics and how many students preferred which topic. Rather than just focusing on one topic that was chosen centrally, the mode helps gather data.
Hope this helps!

Using cosine we can find the value of X:
COS 29,37° = X/32
X = 32 . COS 29,37
<h3>X ≈ 27,89</h3>
