C I'm using the calculator and the other ones don't make sense
We are given the following function and want to find the y-intercept:

Just substitute the value x=0 into the equation to find the value of the y-intercept:

Simplify

Simplify again

Since the value of f(x), or y, when x=0 is 66, the y-intercept of this function is 66.
Let me know if you need any clarifications, thanks!
