Given f(x) = -3x - 7 and g(x) = x4, choose
the expression for (fºg)(x).

x^8+7x^4

Step-by-step explanation:

First we have to do the g(x) cause it's closest to x.

g(x)=x^4

x^4 is the output for g(x) ad input for f(x). So now we have to put it in x's place in here➡️f(x)

So, f(x^4)=(x^4)^2+ 7(x^4)

=x^8+7x^4

It's the final output

step-by-step explanation:

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
