Question

Given the function f (x)=2^x.What is the value of f(-3)?​

Answer 1

f(-3)= -8

Explanation:

If f(x)= 2^x and x has been substituted for -3 then it means it's now 2^-3 which is going to give you

= -2 × -2 × -2

= 4 × -2

= -8

Answer 2

1/8

Explanation:

`f(x)=2^x\\\\f(-3)=2^(-3)\\\\f(-3)=(1)/(2^3)\\\\\boxed{f(-3)=(1)/(8)}`

Hope this helps!
