Question

Point B is on the graph of the function f(x) = -3x2. If the x-coordinate of point B is 2, which ordered pair gives the location of point B?

Answer 1

Answer:

-4

Step-by-step explanation:

-3x + 2 =y

-3(2) + 2 = y

y=-4

Answer 2

Answer:

(2, -12)

Step-by-step explanation:

It's f(x) = -3x^2.  The " ^ " symbol indicates exponentiation.

If x = 2, y = -3(2)^2 = -3(4) = -12

So the ordered pair in question is (2, -12).
