A function can have one x-value for each y-value Or even, two difference x-values for one y-value.

And out of the four options, only A and C represent a function. The other two options have the same x value for two y-values.

One way to test if it is a function is by the vertical line test.

Sindrei [870]

Answer:

D) 42.16

Total: $553.13

Step-by-step explanation:

Multiply the subtotal, 510.97, by 8.25%. To do that just turn the 8.25% into a decimal which is 0.0825. The answer to that would be 42.155025 and rounded it would be 42.16 so the tax would be $42.16.

The total to the entire thing would be $553.13 since you just add the tax and subtotal together.
