Graph: f(x) = 22-1 Step 1: Find the value of x that makes the exponent zero
by solving this equation: x-1 = 0

Step-by-step explanation:

To graph an exponential function f(x) = ,

Step - 1 :

Find the value of x that makes the exponent 0.

x - 1 = 0

x = 1

f(1) = 2⁰ = 1

Similarly, for other input values (x- values),

For x = 2,

f(2) =

     = 2¹

     = 2

For x = 3

f(3) =

     = 2²

     = 4

For x = 4

f(4) =  

     = 2³

     = 8

Therefore, table for input - output values will be,

x        1            2            3          4

f(x)     1            2            4          8

b) 36
