Janelle and her best friend Carmen go shopping. The function p(x) = 5x^4 − 3x^3 + 2x^2 + 24 represents how much money each girl spent based on the number of hours they were shopping. If Janelle and Carmen each go shopping for 2 hours, how much money did they spend together? $58
$62
$176
$124.

do not try to answer for points or I will delete your answer

p(x) = 5x^4 − 3x^3 + 2x^2 + 24

for x = 2

=>

p(2) = 5(2)⁴-3(2)³+2(2)²+24

= 80-24+8+24

= 88

so, the numbers of money that they spend together = 2×88 = $176

The correct answer is A) as the x values go to positive infinity, then the graph goes to negative infinity.

We can tell this by looking at the graph values as x goes up. You'll notice, as we get higher and higher, the graph disappears down. This means it is heading towards negative infinity for the rest of the graph.
