Answer:

-21

Step-by-step explanation:

We know that $f(x)=-x^2-12$ and we also know that $f(x)=f(-3)$ . Therefore, you will have to substitute x with -3.

<u>Calculations:</u>

$f(x)=-x^2-12$

$f(-3)=-(-3)^2-12$

$-9-12=-21$

The coordinates of the midpoint of the two vertices are

(0,2) (Third option)

Step-by-step explanation:

<u>Coordinates Of A Midpoint </u>

Given a pair of points in the plane

$\displaystyle P_1\ (x_1,y_1)\ ,\ P_2(x_2,y_2)$

the coordinates of the midpoint of both points are

$\displaystyle x_m=\frac{x_1+x_2}{2}$

$\displaystyle y_m=\frac{y_1+y_2}{2}$

The vertices given in the figure are

$\displaystyle v_1(-4,1),\ v_2\ (4,3)$

So the x-coordinate of their midpoint is

$\displaystyle x_m=\frac{-4+4}{2}=\frac{0}{2}=0$

And the y-coordinate of their midpoint is

$\displaystyle y_m=\frac{1+3}{2}=\frac{4}{2}=2$

So the coordinates of the midpoint of the two vertices are

(0,2), the third option

(a)Use differentiation to find the minimum value of f(x)= 3x^2 - 5x + 10 and the value(s) of x for which this minimum occurs.

Hi there!

Begin by differentiating f(x) using the power rule:

dy/dx = nxⁿ⁻¹

Therefore:

f(x) = 3x² - 5x + 10

f'(x) = 6x - 5

Set this equation equal to 0 to find the x-intercept:

0 = 6x - 5

5 = 6x

x = 5/6, which is where the graph goes from NEGATIVE to POSITIVE, so there is a MINIMUM at this value.
