Question

((8x+13)+(x2-5x))(x) how would you solve for that???

Answer 1

Distribute the "x" first.

Answer 2

I thought whatever is in the parentheses, is like solved first?

Answer 3

Is this the multiplication of the quantity and x?

\( \large [(8x+13)+(x^2-5x)]x\)

Answer 4

i do not think so

Answer 5

Then what is the problem?

Answer 6

Btw, its problem number 2

Answer 7

I got it.

Answer 8

Here are the two functions f and g.

\(f(x) = 8x + 13\)

\(g(x) = x^2 - 5x\)

2.
\((f + g)(x) = f(x) + g(x)\)

\((f + g)(x) = 8x + 13 + x^2 - 5x\)

\((f + g)(x)= x^2 + 3x +13\)

Answer 9

All you need to do for 2. is to add the functions f and g.

Answer 10

ooooh okay, THANKYOU SO MUCH!!

Answer 11

You're welcome.

Answer 12

what about number 11? How would you find the composite function?
do you plug in and solve or something else?

Answer 13

For composite functions, plug in the inner function into x of the outer function.

11.
\(f(g(x)) = f(2x - 3) = (2x - 3)^2\)
