Answer:

f(-2) = 4
f(1) = -5
D: [-3, ∞)
R: [-5, 11]

Step-by-step explanation:

You have marked the points on the graph corresponding to ...

f(-2) = 4

f(1) = -5

The domain is the horizontal extent, from x = -3 to +∞.

The range is the vertical extent, from y = -5 to +11 (inclusive).

Mr. Stanley bought a car that was marked down 18%.

Lady bird [3.3K]

Answer:

P=100-0.18

Step-by-step explanation:

Remember, percent means per every 100. So if the car cost $100, Mr. Stanley saves $18 on the car. Also, 18%= 0.18. And just for extra, single digit percents would be expressed with an extra zero in front of it, such as 5%=0.05.

Given the function h(a) = -x^2+ 7x + 14, determine the average rate of change

Yakvenalex [24]

Answer:

- 2

Step-by-step explanation:

The average rate of change of h(x) in the closed interval [a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [a, b ] = [1, 8 ], thus

f(b) = f(8) = - 8² + 7(8) + 14 = - 64 + 56 + 14 = 6

f(a) = f(1) = - 1² + 7(1) + 14 = - 1 + 7 + 14 = 20

average rate of change = $\frac{6-20}{8-1}$ = $\frac{-14}{7}$ = - 2
