Answer:
3 times
Step-by-step explanation:
Take out a ruler and draw a horizontal line through y = 1. It should become obvious immediately that this horizontal line intersects the graph 3 times.
F(x) = 25 - 2x
f(5) is pretty much the value of f(x) when x = 5
Plug x=5 into f(x)
f(5) = 25 - 2(5)
= 15
That's your answer.
Have an awesome day! :)
