Consider the function f, which is a one-to-one function with values f(3) = 2 and f(-4) = 8.
Which of the following must be true?
A.) f^-1(8)=3
B.) f^-1(2)=8
C.) f^-1(3)=-2
D.) f^-1(2)=3
E.) f^-1(8)=-4
F.) f^-1(-4)=-8

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

What value of x is in the solution set of 4x – 12 s 16 + 8x?

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
