Question

Use the graphs of f and g shown below to find the following:

(a) g (f (2)) ≈
(b) f (g (4)) ≈
(pic will be posted)

Answer 1

As an example, for A, what is f(x) when x = 2?

Answer 2

Would that be y=1?

Answer 3

Yes, Now put 1 in for x in the g(x) graph and what do you get?

Answer 4

Would that be y=2?

Answer 5

Thats it.

Answer 6

So that means g(f(2))=2?

Answer 7

Yes indeed.

Answer 8

Thank you so much! So would that mean B. is f(g(4))=4?

Answer 9

That's not what I'm getting. What's g(4) ?

Answer 10

x=4 when y=1?

Answer 11

Correct, but worded incorrectly. Y=1 when X = 4.
Now what is f(1) ?

Answer 12

y=-2 when x=1?

Answer 13

Yes, so f(g(4)) = -2

Answer 14

Thank you so much!

Answer 15
