Question

Here's another thing I must solve:

For each graph of a function, determine these things:

a. f(1)
b. domain
c. any x-values for f(x)=2
d. range

I can't put the graphs I need up here, but is anyone able to explain how you would find these things?

Thank you so much!

Answer 1

a. f(1) is the value of y where x = 1 on the curve that must appear on your graph. The y axis shows the value of f(x) at each x.

b. The domain extends from the lowest to the highest x values on the graph

c. read off the x values wher y = 1

d. The range extends from the lowest to the highest y values on the graph.
