I am having to find the value of y for the given values of x. I understand how to find the value of x, but I am unsure how to put it in the form of ordered pairs:

Question

This is not the actual problem on my assignment:

y=7^x, for x=2

y=7^2
y=7*7
y=49

I am lost as to how I put it in ordered pairs: Would it be (2,49)?

I am not looking for the answer, just some guidance! Thanks!

Answer 1

I am also unclean if the exponent is negative, such as -2, does the ordered pair go in as (-2, 1/2)?

Answer 2

if x = -2 for y = 7^x
then
y = 7^(-2) = 1/7^2 = 1/49

ordered pair: (-2,1/49)

this is using the rule,
a^(-n) = 1/a^n

Answer 3

thanks!
