Answer:
f(-2) = 4
Step-by-step explanation:
The function has three definitions depending on the value of x.
You are looking for the value of the function at x = -2.
-2 is in the interval x <= -1, which is the first line of the definition of the function.
We use the first line of the definition of the function.
f(x) = -2x for x <= -1
f(-2) = -2(-2) = 4
Answer: f(-2) = 4
Answer:
5x² - 31x + 30
Step-by-step explanation:
(5 - x)(6 - 5x)
= 30 - 25x - 6x + 5x²
= 30 - 31x + 5x²
= 5x² - 31x + 30
