Question

Which is true regarding the graphed function f(x)?

• f(O) = 3
• f(5) = - 1
• f(3) = 2
O f(2) = -2

Answer 1

f(5) = -1

Explanation:

The points on the graph are (0,4), (1,3),(2,2), (3,1), (4,0), (5,-1).

The answers are in the form:

f(x) = y

That is, the number in the parenthesis is the x and the number by itself on the right is the y. The only one that is a point on the line is f(5) = -1, which is the point (5,-1)
