Answer:
Correct option: first one
Step-by-step explanation:
The equation f(x) = 5x + 1 is a function, because each value of x gives only one value of y.
Now let's find the inverse by switching f(x) by x and x by f'(x), then isolating f'(x):
The inverse f'(x) is also a function, because each value of x gives only one value of x.
So we have that both the equation and its inverse are function, therefore the correct answer is the first option.

Answer: B
Step-by-step explanation:
<u>if 4w-1 ≥0</u> or w > 1/4 then
|4w-1|=4w-1
4w-1=5w+37 ==> w=-38 (exclude since not >1/4)
<u>else</u>
4w-1 < 0 or 4w <1 or w < 1/4
|4w-1|=-(4w-1)
-(4w-1)=5w+37
-4w+1=5w+37
9w=-36
w=-36/9
w=-4 ( which is < 1/4)
