Question

Select all point that are on the graph of f if we know that f(2)=-4 and f(5)=3.4.

(-4,2)
(2,-4)
(3.4,5)
(5,3.4)
(2,5)

Answer 1

Answer:

(2,-4) , (5,3.4)

Step-by-step explanation:

I did it and got it right.

Answer 2

Based on the information given by the function input and output, all the possible points on the graph would be ;

• (2, -4)

• (5, 3.4)

The input of a function is the x - coordinate of a graph while the output produced is the y-coordinate of the graph.

Hence,

When, f(2) = -4

x = 2 ; y = - 4

When ; f(5) = 3.4

x = 5 ; y = 3.4

The pair of points from the firsts statement = (2, -4)

The pair of point from the second statement = (5, 3.4)

Hence, two pairs of point on the graph are :

• (2, - 4) and (5, 3.4)
