Question

HELP PLEASE!
How do i solve this? step by step
f(x)=2^x-1 g(x)=sqrt x

Answer 1

what are we solving? you just gave 2 functions?

Answer 2

I have to find the approximate solutions. then i have to graph it.

Answer 3

i can do the graphing

Answer 4

wait are the vertices the approx. values?

Answer 5

i dont understand, to solve an equation you need something on left side and right side

2^x-1 = ? sqrt(x) = ?

Answer 6

Page 3 problem 1

Answer 7

Unless i have to somehow put tem together and use the quadratic equation

Answer 8

the worksheet doesn't really explain anything but if these are meant to be supply/demand functions then maybe the solutions are supposed to be the equilibrium point
f(x) = g(x)

2^x -1 = sqrt(x)

if you graph both functions you will see that they both meet at the origin and at 1 other point
use graphing software to estimate the point
you cant solve this using algebra

Answer 9

Oh Okay Well Thank You Anyway! And Yeah I Graphed Them But Didnt think that could be it.

Answer 10

the picture has f(x) = 2^x
your post has f(x)= 2^x-1

Answer 12

No thats the very first problem which ive already done i mean the first problem under solving systems graphicaly on page 3 look again :)

Answer 13

Thank You So Much!

Answer 14

I see the other problem as well
did you get the solution?

Answer 15

Yes yes i did :)
