Question

Graph: f(x) = 22-1

Answer 1

Answer:

Step-by-step explanation:

To graph an exponential function f(x) = $2^{x-1}$,

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) = $2^{2-1}$

     = 2¹

     = 2

For x = 3

f(3) = $2^{3-1}$

     = 2²

     = 4

For x = 4

f(4) = $2^{4-1}$  

     = 2³

     = 8

Therefore, table for input - output values will be,

x        1            2            3          4

f(x)     1            2            4          8
