Answer:

-1/2

Step-by-step explanation:

If you connected the dots here you would have a straight line. The average rate of change for a straight line is also known as the slope. Slope, by definition, is rise over run (although rise doesn't necessarily mean "up"; it could also mean down, as it does here). From one point to the next in our graph, we go down 1 unit (-1) and to the right 2 units (+2). Therefore, the slope of the line is -1/2.

Find f(3).<br><br> f(x) = x2 + 5x - 9<br> A) 7 <br> B) 10 <br> C) 9 <br> D) 15

Lelechka [254]

Answer:

f(3) = 15. Correct: D)

Explanation:

<u>Numeric Value of a Function</u>

The value of a function f(x) when x = a is calculated by replacing the x for a. We have the function:

$f(x)=x^2+5x-9$

It is required to find f(3), or the numeric value of f when x=3. Replace x for 3

$f(3)=3^2+5(3)-9$

$f(3)=9+15-9$

$f(3)=15$

A) Incorrect. f(3) is not 7

B) Incorrect. f(3) is not 10

C) Incorrect. f(3) is not 9

D) Correct. f(3) =15 as found above.

Answer:

2 and 6 for the circles.

-18 for the square.

Step-by-step explanation:

-3 times a number is -6.

$-3 \times 2 = -6$

The number is 2.

2 times a number is 12.

$2 \times 6 = 12$

The number is 6.

6 times -3.

$6 \times -3 = -18$

The number is -18.
