Question

Can someone please walk me through this problem?
The function f is defined by the following rule,
f(x) = (1/4)^x
Find f(x) for each of these five values

x | f(x)
_ | _______________|
-2 |_______________|
-1 |_______________|
0 |_______________|
1 |_______________|
2 |_______________|
___________________|

Answer 1

You just plug the numbers in for x
First one: (1/4)^-2=16
Second one: (1/4)^-1 = 4
Try the rest on your own. Let me know if you need more help :D

Answer 2

I'll do just 1

Y=f(x)
Y=(1/4)^x

Y=(1/4)^(-2)=1/(1/4)²=1/(1/16)=16

Answer 3

Thank You :)
