Answer:
f(- 2) = 20
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = (- 2)² - 5(- 2) + 6 = 4 + 10 + 6 = 20
The value of the function f(x) = x² - 5x + 6 at x = -2 is 20 after plugging the value of x is -2 in the function.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = x² - 5x + 6
Plug x = -2
f(-2) = (-2)² - 5(-2) + 6
f(-2) = 4 + 10 + 6
f(-2) = 20
Thus, the value of the function f(x) = x² - 5x + 6 at x = -2 is 20 after plugging the value of x is -2 in the function.
