Question

If you are given the graph of g(x)=log2x how would you graph f(x)=log2x+5

Answer 1

You would translate  g(x) 5 units up  
First choice.

Answer 2

Answer: A) Translate each point of the graph of g(x) 5 units up.

Step-by-step explanation: We are given logarithm function $g(x) = log_2(x)$.

Transformed function is $f(x)=log_2(x)+5$.

According to the rules of transformations,

The transformed function y= f(x) + C would be shift C unit up of f(x) function.

Note: Graph shift C units up if we add any value C to the given function.

If we compare f(x) + C by $log_2(x)+5$, we can see that  value of C is 5.

Therefore, g(x) is being shifted 5 units up.

So, the correct option is :

A) Translate each point of the graph of g(x) 5 units up.
