Question

Complete the missing parts of the table for the following function y=7^x

Answer 1

x= -2 y = (
`(1)/(49)`)

x= 0 y = 1

x= 2 y = 49

Explanation:

x= -2 -> (7)² = 49, negative power makes it inverse to a fraction

y = (
`(1)/(49)`)

x= 0 -> anything to the power of 0 is always 1

y = 1

x= 2 -> 7² = 7 × 7 = 49

y = 49
