Question

Please help! Will fan and medal

Answer 1

Match each operation involving f(x) and g(x) to its answer.
f(x)= 1 - x^2 and g(x) = sqrt( 11-4x)

Pairs:
-3 sqrt3 ------- ______
sqrt15 ------ _____
sqrt3 - 3 ----- _____
0 ----- _____

a. (g+f)(2)
b. (g * f)(2)
c. (g - f)(-1)
d. (f/g)(-1)

Answer 2

fill in the blanks

Answer 3

I need to pair them so what letter goes with -3 sqrt3 and so on

Answer 4

Answer 5

Given:
f(x)= 1 - x^2 and g(x) = sqrt( 11-4x)
So calculate each one and find out:
(g+f)(2)=g(2)+f(2)
=sqrt(11-4(2)) + (1-2^2)
=sqrt(3)+-3
=sqrt(3)-3
Now look for the match.

So similarly for the other 3 and try to find a match.
If you don't find a match, post your work and we can take it from there.

Answer 6

I just realized that I already did this. Lol I posted the wrong question

Answer 7

Ok, that's a good sign, but what's important is you know \(how\) to solve the problem.!

Answer 8

Oh yes, of course. Not knowing how wouldn't help me learn at all.

Answer 9

Here's the question I actually needed help with right now:


The total daily cost (in dollars) of manufacturing scented candles is given by the function C(b) = 250 + 3b, where b is the number of candles manufactured. Which function represents the average manufacturing cost, A, in terms of b?

a. A(b) = b / 250+3b
b. A(b) = 250+3b / b
c. A(b) = (250 + 3b) * (b)
d. A(b) = 250 + 4b

Is the answer c?
