Answer:
Differentiable on the intervals (-∞, -5) ∪ (-5 , 5) ∪ (5 , ∞)
Step-by-step explanation:
The graph will look like a W shape whose vertices are at x = -5 and x = 5. The function is not differentiable at these values.
Step-by-step explanation:
It's the equation of a line.
We need only two points to the plotting a graph of a line.
y = -x - 3
for x = -3
y = -(-3) - 3 = 3 - 3 = 0 → (-3, 0)
for x = 0
y = -0 - 3 = 0 - 3 = -3 → (0, -3)
Answer:
−32^2−20
Step-by-step explanation:
Answer:
(x+2)(x-1)
Step-by-step explanation:
One way to factor is to FOIL your answer choices:
First: x(x)
Outer: x(-1)
Inside: 2(x)
Last: 2(-1)
Combine these values together and you get
x^2-x-2
