Complete the table and then determine which of the following is the graph of ƒ(x) = 2√x
2 answers:
F(0)=0
f(-1) is undefined, so no negatives
f(4)=4
2nd graph
Answer:
Hi!
The second graph corresponds to ƒ(x) = 2√x.
Step-by-step explanation:
First, √x for x < 0 does not have solutions on reals numbers.
For example:
x = -4, √-4 does not have solution because (-2)*(-2) = 4 and 2*2 = 4.
The table for ƒ(x) = 2√x
- f(2) = 2√2 = 2*1.41 = 2.82
- f(3) =2√3 = 2*1.73 = 3.46
- f(5) =2√5 = 2*2.23 = 4.46
