4^x • 4^y = 1024
What is x + y?

x + y = 5

Step-by-step explanation:

x + y = 5

Step-by-step explanation:

using the rule of exponents

× = , then

× = , so

= 1024 =

x + y = 5

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
