Decide whether the function is one to one.

y= - (x+3)^2-8

  it is NOT one-to-one

Step-by-step explanation:

A one-to-one function must pass the vertical line test (in order to be a function) and the horizontal line test (in order to be one-to-one).

No even-degree polynomial function will pass the horizontal line test. This function is even degree (2), so is not one-to-one.

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

i would pic false cause it goes down towards negative
