Which statement describes the mapping?

icang [17]

Answer:

Third one

Step-by-step explanation:

To be a function x must only have 1 y value or you're really describing a limit which isn't part of the outputs

However, In your case two x values equaling the same y value is fine because the x values do not have two y values

This is a function, as each x value corresponds to one y value

My apologies I was confused with my first answer.

Answer:

$p(20) = 4460$

Step-by-step explanation:

Given

$p(x) = -10x^2 + 498x - 1500$

Required

Evaluate p(x) when x = 20

To do this, we simply substitute 20 for x

$p(x) = -10x^2 + 498x - 1500$

$p(20) = -10 * 20^2 + 498 * 20 - 1500$

$p(20) = -10 * 400 + 9960 - 1500$

$p(20) = -4000 + 9960 - 1500$

$p(20) = 4460$
