Question

What is the y intercept of the exponential function? f(x)= - 1/3 (3)^(x+3) -1

Answer 1

Answer:

y- intercept = - 10 or (0, - 10 )

Step-by-step explanation:

to find the y-intercept, that is where the graph crosses the y- axis let x = 0 in the equation

f(0) = - $\frac{1}{3}$ (3)³ - 1

     = - $\frac{1}{3}$ × 27 - 1 = - 9 - 1 = - 10
