Which ordered pair represents F(3) = -5
a) (-3,5)
b) (-5,3)
c) (5,-3)
d) (3,-5)
a) (-3,5)
b) (-5,3)
c) (5,-3)
d) (3,-5)
-
D, because since in a function, you have F(x) equaling something, whatever's in the parentheses is the x value, and the number on the outside is the y value.
-
You are plugging 3 into the function for every x. That is like saying y(3)=-5 so your y coordinate is -5 when you plug 3 into the function. The answer is D)
-
B. in a function, F(x) is also known as the Y value.
