Answer:
The output value of f(-2) is, 14
Step-by-step explanation:
Given the function:
[tex]f(x) = x^2-3x+2[/tex] ......[1]
We have to find the output of f(-2).
Substitute x = -2 in [1] we have;
[tex]f(-2) = (-2)^2-3(-2)+2[/tex]
⇒[tex]f(-2) = 4+6+2[/tex]
Simplify:
[tex]f(-2) = 12[/tex]
therefore, the output value of f(-2) is, 12
