The function f is defined by the following rule. f(x)=3*

Find f (x) for each x-value in the table.

Since f(x) = 3^x,
for x = -3,
f(x) = f(-3) = 3⁻³ = 1/3³ = 1/27

for x = -2,
repeat the same steps and you will get 1/9

for x = -1, repeat again to get 1/3
basically the general rule for negative exponents, is to get the reciprocal of the base, then calculate the exponent.

for x = 0,
f(x) = f(0) = 3⁰ = 1
this is because any number to the power of 0 is 1.

for x = 1,
f(x) = f(1) = 3^1 = 3
which I'm sure you understand why
Hope this helps
