Answers:

Functions

  • y = -x+11
  • y = 2x^2-6x+4
  • y = -7

Not functions

  • x = 3
  • x^2+y^2 = 81
  • y^2 = -5x-12

=======================================================

Explanation:

A function is possible if and only if any given x input leads to exactly one y output.

For something like x^2+y^2 = 81, we can see that x = 0 leads to either y = 9 or y = -9. So this would <u>not</u> be a function. We would need x to pair with only y value to have it be a function.

We have the same thing going on with y^2 = -5x-12 as well.

For anything of the form x = k, where k is any real number, this is also not a function. We have one single input only and it leads to infinitely many outputs. So in a sense, this is even worse compared to the other examples.

-----------------

In summary, we have these three non-functions:

  • x = 3
  • x^2+y^2 = 81
  • y^2 = -5x-12

Everything else is a function. You can use the vertical line test as a visual way to check.

Question 2 of 15. Step 1 of 1
azamat

Answer:

  A = -68.75p +2906.25

Step-by-step explanation:

We can solve for m and b using the given values of A and p.

  1600 = m·19 +b

  2150 = m·11 +b

Subtracting the second equation from the first, we have ...

  -550 = 8m

  m = -550/8 = -68.75

Substituting this into the first equation gives ...

  1600 = 19·(-68.75) +b

  b = 1600 +1306.25 = 2906.25

The desired linear equation is ...

  A = -68.75p +2906.25
