Don't know what to do :\\
____ [38]
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.

A cake recipe calls for 1 cup of oil. Jean needs to make 12 cakes for her school bake sale. How many quarts of oil will Jean nee
kipiarov [429]
Hey there,

Each cake recipe would call for \boxed{1} cup of oil.

So if she is going to make 12 cakes, this would include that she
would need to use 12 cups of oil.

\boxed{12} would be your answer!

Hope this helps.
