Question

Please Solve the following #6 and #7. Answer: C, A

Answer 1

6) For the inverse to be a function, f(x) needs to be one to one. To accomplish this, restrict the domain to one side of the axis of symmetry

7) The y-intercept of the inverse is when x=0. This means we want to find when f(x)=0.

`4(1/3)^x = 16 \\ \\ (1/3)^x= 4 \\ \\ x=\log_(1/3)(4) \approx -1.26`
