Answer:

x = - 8, x = 2

Step-by-step explanation:

Given

f(x) = x² + 6x - 16

To find the x- intercepts equate f(x) to zero, that is

x² + 6x - 16 = 0 ← in standard form

(x + 8)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 8 = 0 ⇒ x = - 8

x - 2 = 0 ⇒ x = 2

You are currently paying rent every year for your restaurant. You still have a contract that will last 2 more years. Starting to

Andreas93 [3]

The amount to be paid in rent after 2 years if the rent as of now is $3,000 will be; $3,213.675

The question allows that we choose the amount being paid as rent as of now.

Let the rent paid as of now be; $3,000

In essence; after the first year; the amount increases by 3.5% to become;

1.035 × $3,000

= $3,105.

After the second year; we have;

1.035 × $3,105

= $3,213.675

Ultimately; the amount to be paid after 2 years will be; $3,213.675.

When given the opportunity to change rent contracts;

A situation that will be beneficial would be a 3.5% reduction in rent per year
A situation that will not be beneficial would be a 7% increase in rent per year.

Need help finding intervals where the function is decreasing.

umka21 [38]

$f(x)=-5x-5\sin x\implies f'(x)=-5-5\cos x$

$f$ is decreasing on some interval $(a,b)$ if $f'(x)$ for all $x\in(a,b)$ . Similarly, $f$ is increasing on $(a,b)$ if $f'(x)>0$ for all $x\in(a,b)$ .
