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:
A = x^2 + 4x -21
Step-by-step explanation:
L = x+7
W = x-3
A = L*W
A = (x+7)(x-3)
A = x^2 + 4x - 21
Answer:
line
Step-by-step explanation:
that is a line in the form y = mx + b
slope = m = 3
y intercept = b = 7
1st one is the y Intercept is 5. get y by itself 12y=-6x+60 divide by 12.
2nd slope is -3
