Answer:

The maximum is -3

and the third one -3<f(x)≤ -3

Step-by-step explanation:

Let's start by expanding the exponent

-(x+7)²= -(x²+14x+49)= -x²-14x-49

simplify

-x²-14x-49-3= -x²-14x-52

To find the maximum/minimum take the first derivative

-x²-14x-52= -2x-14

set this equal to 0

-2x-14= 0

x= -7

We then plug in x= -7 into the equation to find the y value

Because the coeficcent for the degree is negative (it's -1) this is a maximum

-(-7+7)²-3 = -3

Because -3 is the highest point the graph's range is -∞<f(x)< -3

Therefore the maximum i

Then, 3 shirts cost 3 times as much as x, or 3x.
She spent 3x.

3x + 9 = 30

Answer:

<h3>{44-55}</h3><h3>{52- 59 } are the last two interval s</h3>

Step-by-step explanation:

<h2>To get the class boundaries deduct 0.5 from the first number and add 0.5 to the second number = 4-0.5 = 3.5 </h2><h2> = 11.5 + 0.5 = 11.5 </h2><h2> = 3.5 -11.5 as in the fish class boundary .</h2><h2>same for all other boundaries</h2>
