Question

6. Which of the following is the graph of the following function?

Answer 1

The answer is the third graph.
What ever number is for X you have to turn it into a positive. So lets say the value of X is -2, you turn it into a positive 2. Then multiply 2 by 2 to get four. So f(x) would equal positive 4.

F(x) is another way of saying Y.
