Answer:

2x² - 2x

Step-by-step explanation:

- 6x + 2 - (- 2x² - 4x + 2) ← distribute parenthesis by - 1

= - 6x + 2 + 2x² + 4x - 2 ← collect like terms

= 2x² - 2x

Step-by-step explanation:

-6x+2-(-2x^2-4x+2)

-6x+2+2x^2+4x-2

2x^2-6x+4x+2-2

2x^2-2x

2x(x-1)

F(x) = x^2-3<br> What is the average rate of change on the interval [-5, 2] ?

Mumz [18]

Answer:

$(-3)$ .

Step-by-step explanation:

Over this interval, the change in the value of this function is:

$f(-5) - f(2) = 22 - 1 = 21$ .

The corresponding change in the value of $x$ :

$(-5) - 2 = -7$ .

The average rate of change of function $f$ over this interval is equal to the change in the function value divided by the corresponding change in $x$ :

$\begin{aligned}& (\text{average rate of change}) \\ =\; & \frac{(\text{change in function value})}{(\text{change in $x$})} \\ =\; & \frac{f(-5) - f(2)}{(-5) - 2} \\ =\; & \frac{22 - 1}{-7} \\ =\; & \frac{21}{-7} \\ =\; & -3\end{aligned}$ .

Thus, the average rate of change of $f(x) = x^{2} - 3$ over the interval $[-5,\, 2]$ would be $(-3)$ .
