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) = - [tex]\frac{1}{3}[/tex] (3)³ - 1
= - [tex]\frac{1}{3}[/tex] × 27 - 1 = - 9 - 1 = - 10
Answer:
-10
Step-by-step explanation:
f(x) = [tex]-\frac{1}{3}[/tex][tex](3)^{x+3}[/tex] - 1
f(0) = [tex]-\frac{1}{3}[/tex] [tex]3^{3}[/tex] - 1 = [tex]-\frac{1}{3}[/tex] · 27 - 1 = -9 - 1
= -10
have a miraculous day!! :D
