Question

PRECALC help will fan and medal and attach the problem

Answer 1

You get the inverse of a function by reflecting it over the line y=x. (You may reacall from algebra that sometimes when want to find the inverse of a function and you switch y and x and solve for y because y=x.)

Answer 2

okkkk

Answer 3

So, let's say you have the point (3,0). It's inverse would be (0,3). You just switch x and y.

Answer 4

k i think im kinda getting it

Answer 5

Because the inverse of a graph is reflected over the y-axis, the y-axis is the line of symmetry. So the function (graph) and its inverse are symmetrical about the y-axis. (You can elminate the 2nd answer choice).

Answer 6

ok

Answer 7

Then if you draw in or imagine the line y=x there and turn you head, you can see that graph f is definitely not symmetrical with graph h over the line y=x.

Answer 8

mhm

Answer 9

ohh ok so then it would be g

Answer 10

ohh ok

Answer 11

Ok I confused myself. So the answer is that f and g are inverses symmetrical about the line y=x. (Choice 3)

Answer 12

And you can check with the point (3,6), which is on graph f. It's inverse, (6,3), is also on graph g.

Answer 13

so is that the answer?

Answer 14

Yes

Answer 15

ok thank you so much i think i have another question could you help me with that too?

Answer 16

Sure I can try
