Answer:
-33
Step-by-step explanation:
To solve this problem
substitute -3 for x
f(-3)= 3(-3^3) + 7(-3)^2 +5(-3)
f(-3) = 3(-27) + 7(9) -15
f(-3) = -81 +63 - 15
f(-3) = -18 -15
f(-3) = -33
Answer:
[tex]f(-3)=-33[/tex]
Step-by-step explanation:
Function : [tex]f(x) = 3x^3 + 7x^2 + 5x[/tex]
We are supposed to find [tex]f(-3)[/tex]
Substitute the value of x = -3 in given function
[tex]f(x) = 3x^3 + 7x^2 + 5x[/tex]
[tex]f(x) = 3(-3)^3 + 7(-3)^2 + 5(-3)[/tex]
[tex]f(x) = 3(-27) + 7(9) + 5(-3)[/tex]
[tex]f(x) = -33[/tex]
Hence [tex]f(-3)=-33[/tex]
