Answer:
f(x)=-1 and 15
Step-by-step explanation:
What you do is you put -2 and 2 into the x.
f(x) = -4(-2) + 7 = -1
f(x) = -4(2) + 7 = 15
f(x)=-1 and 15 are your answers.
Answer:
Answer:
See the graph attached. The red arrow represents the shaded area.
Explanation:
The inequality and its solution are given:
The solution set is all real numbers less than or equal to -50.
In a number line, the values less than -50 are all the values that are to the left of -50. Thus, the graph of a ≤ -50 must include -50 and the region to the left of it.
To indicate that - 50 is included, draw a solid point; then, shade the region since it to its left.
Please, see the graph attached. The red arrow represents the shaded area.
Step-by-step explanation:
A) intercepts: zero profit; maximum: maximum profit. increasing: x < 4; decreasing x > 4
B) average slope: ≈50, about $50 increased profit for each $1 increase in price.
no, it is constant for a while then changes at 90gallons
