6. given the function rule f(x) = x^2 - 3x + 2, what is the output of f(-2)?
a. -8
b. 0
c. 4
d. 12**
please help!!!
f(-2) = (-2)^2 - 3*(-2)+2=4+3*2+2=4+6+2=12
agree
To find the output of the function f(x) = x^2 - 3x + 2 when x = -2, substitute -2 into the equation.
f(-2) = (-2)^2 - 3(-2) + 2
Simplifying further:
f(-2) = 4 + 6 + 2
f(-2) = 12
Therefore, the output of f(-2) is 12.
So, the correct answer is d. 12.
To find the output of a function, you need to substitute the given input into the function and evaluate it. In this case, you are given the function f(x) = x^2 - 3x + 2 and asked to find f(-2).
To find f(-2), substitute -2 for x in the function f(x):
f(-2) = (-2)^2 - 3(-2) + 2
= 4 + 6 + 2
= 12
Therefore, the output of f(-2) is 12. So, the correct answer is option d.
