Kayla and her best friend christina go shopping. the function p(t) = 2x4 + 6x3 - 3x2 + 24 represents how much money each girl spent based on the
number of hours they were shopping. if kayla and christina each go shopping for 2 hours, how much money did they spend together?
$44
$88
$92
$184

LAST OPTION.

Step-by-step explanation:

You have the following function that  represents the amount of money each girl spent:

Where "t" is the  number of hours they were shopping.

You know that each girl went shopping for 2 hours.

Then, you can substitute into the given function:

Evaluating, you get that the amount of money spent by one of these girls in 2 hours, is:

Therefore, the total amount of money Kayla and her best friend Cristina spent together is:

This matches with the last option.

i got 142 as my answer

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
