Answer:

[tex]f(-4)=68[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x) = 3x^2 - 5 x[/tex]

And we want to find f(-4).

So, we will substitute every x for -4. This yields:

[tex]f(-4)=3(-4)^2-5(-4)[/tex]

Evaluate:

[tex]f(-4)=3(16)-(-20)=48+20=68[/tex]

So, f(-4) = 68.

Answer:

26

Step-by-step explanation:

(3*2) + (-5*-4)

6 + 20 = 26
