The answer is B. In this case when you isolate the variable it just takes 2 steps. The others require more steps and tedious calculation.

Answer: Choice A) 12x^2 - 48x + 21; all real numbers

===========================================================

Work Shown:

(f * g)(x) = f(x) * g(x)
(f * g)(x) = ( f(x) ) * ( g(x) )
(f * g)(x) = ( -2x+7 ) * ( -6x+3 )
(f * g)(x) = -2x*( -6x+3 ) + 7*( -6x+3 )
(f * g)(x) = -2x*(-6x) - 2x*(3) + 7*(-6x) + 7*(3)
(f * g)(x) = 12x^2 - 6x - 42x + 21
(f * g)(x) = 12x^2 - 48x + 21

The domain is the set of all real numbers because we can plug in any number in for x, to get some output for y. There are no issues to worry about such as division by zero errors, square root of a negative number, etc.

Answer:

<u>3</u> fewer fluids ounces the regular bottle of sunscreen holds.

Step-by-step explanation:

Given:

The family size bottle of sunscreen holds = 12 oz.

The regular bottle holds 75% less.

Now, to find how much fewer fluids ounces does the regular bottle of sunscreen holds.

So, according to question:

$12-75\%\ of\ 12$

$=12-frac{75}{100} \times 12$

$=12-0.75\times 12$

$=12-9$

$=3\ oz.$

Therefore, 3 fewer fluids ounces the regular bottle of sunscreen holds.
