Question

Given the parent function f(x) = 2x, which graph shows f(x) + 1? answer is the photo!

Answer 1

If f(x)= 2^x 

if the question is f(x)+1=      2^(x) +1

the +1 means the graph of f(x) will go up one unit

Answer 2

We are given parent function: $f(x)=2^x.$

We need to explain which graph would represent f(x) +1. function.

Please note: 1 is added to parent function f(x).

According to rule of transformations y= f(x)+K shifts K units up of parent function f(x).

For parent function f(x) =2^x, y-intercept is 1.

So, for f(x)+1 function y-intercept would be 2 because y-intercept 1 is being shifted 1 unit up, that is 2.

So, the shown graph would be correct graph for f(x)+1.
