We can deduce that the graph is a negative parabola from
-0.002x^2. Therefore, the graph is increasing < 1250 and decreasing > 1250.
P(x) is increasing from
and decreasing from
.

Step-by-step explanation:
Answer: Bert's salary didn't increase while Ernie's salary increased by 11 percent.
Step-by-step explanation:
645 / 580 = 1.11
Simple:
1.11 * 100 = 111
100 is a whole so we subtract 100 from 111 to get 11.
11% is our answer.
It doesn't look like Bert's salary changed, 520 =/ 520
Answer:
{-4, 3}
Step-by-step explanation:
To find "solutions," you must set this function equal to zero:
y = -7(x - 3)(x + 4) = 0
and then set each factor equal to 0 separately and solve each resulting equation for x:
x - 3 = 0 yields x = 3, and
x + 4 = 0 yields x = -4
Answer:
40%
