Question

The ordered pairs (1,16 )(2,25)(3,36)(4,49)(5,64) represent a function what Is a rule that represents this function

Answer 1

A. y=x^2
B. y=x+15
C. y=2(x=3)
D. y=(x=3)^2

Answer 2

well all the y values for the points are square numbers....

so that eliminates B and C

so input x = 1 into A and D and see which givens y = 16

then to check use x = 3 to see which gives y = 36
