Question

Which of the following represents the graph of f(x) = 3x – 2 ?

Answer 1

I think your equation should be

\[f(x) = 3^x - 2\]

which is an exponential function....

find the y intercept by letting x = 0

\[y = 3^0 - 2\]

\[y = 1 - 2\]

so the y - intercept is y = -1

find the graph with a y-intercept of y = -1

Answer 2

You're correct my bad, it's a exponential function!

Answer 3

and it is a positive exponential function which generally look like
