Question

How do you solve this Exponential equation?: y = 4 x (the "x" is placed as a square root). need help finding the points and other information, so that I can graph. I understand how to graph, im just struggling getting to that step, because I do not know how to even begin this problem.

Answer 1

Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

Answer 2

to solve
\[y=4^x\]

\[x=\frac{\ln(y)}{ln(4)}\]

Answer 3

oh the x is in a square root!
you are supposed to graph
\[y=\sqrt{x}\]?

Answer 4

points on the graph such as (0,0), (1,1), (4,2), (9,3) etc.
it is the top half of
\[y^2=x\] a parabola with vertex (0,0) facing to the right.

Answer 5

when you said an exponential equation i thought you meant \[y=4^x\] sorry

Answer 6

@ satellite73, no you are right that is the right equation

Answer 7

oh so there is no square root?

Answer 8

or is it
\[y=4^{\sqrt{x}}\]

Answer 9

\[y = 4^{x}\] is the equation

Answer 10

i think it is 4 to the x root, y=4^x

Answer 11

well if is just a matter of graphing
\[y=4^{\sqrt{x}}\] pick some nice numbers and plot some points.
for example pick x= 0, x = 1, x = 4, x = 9, x = 16 (numbers you know the square root of) and see what you get.
(0,0), (1,4), (4,16), (9,64) and so on. you will get a nice exponential graph

Answer 12

the confusion is the word "solve" which usually means write one variable in terms of another or find its value. i think here you meant "solve the problem"

Answer 13

here is a nice picture of
\[y=4^{\sqrt{x}}\]

Answer 14

x \ o \ 1 \ 2 \ 3 \ 4 \ 5 \
----------\------------------------
y=4^(x)\ 1 \ 4 \ 16 \ 64 \256\ 1024 \

Answer 15

awesome! Thank you satellite73, and mark o. !! you guys are life savers!

Answer 16

ok wc, good luck
