Question

Which function rule represents the data in the table below?

Input (x) 1, 2, 3, 4, 5
Output(y) 9, 14, 19 ,24 ,29
a. y=4+5x
b. y=3+6x
c. y=5+4x
d. y=6+3x

Answer 1

Explanation:

a. y=4+5x is the correct answer
because if you substitute the input example
input (x) 4
into the equation y=4+5x
y=4+5(4)
y=4+20
y=24
and when input is 4 the output of the 4th term in output (y) is 24

therefore a. y=4+5x is the right answer
