Question

For the function y=F(x), when x = 4, its y-value is 18.

Answer 1

Answer:

B. The point (4,18) is on the graph of the function

C. The functions value is 18 at 4

D. F(4)=18

Step-by-step explanation:

If the x-value equals 4 when the y-value is 18. This means that F(4)=18 because the 4 is plugged in for the x. Additionally, in a coordinate point, the x-value is given before the y-value. So, if both 4 and 18 are values; then (4,18) must be a point. Also, the function's value is what F(x) equals. Therefore, if F(4)=18 then, the function's value must be 18 when x=4.
