What are the x-intercepts of the graph of the quadratic function f (x) = 3 (x - 1) (x + 3) ?

x=1 and x=-3

Step-by-step explanation:

x-1=0 - --> x=1

x+3=0 - --> x=-3

-3, 1

Step-by-step explanation:

f (x) = 3 (x - 1) (x + 3)

To find the x intercepts, set the equation equal to zero

0 = 3 (x - 1) (x + 3)

Using the zero product property

x-1 = 0 x+3 = 0

x=1 x=-3
