Question

Write an exponential function y=ab^x , for a graph that includes (-3,24) and (-2,12) please i will give a medal to whoever helps me

Answer 1

Write two equations in two unknown a and b and solve them

Answer 2

Yes but how do you set that up

Answer 3

@Nnesha do you know how to solve this?

Answer 4

\[
24=a b^{-3} \\
12=a b^{-2}

\]

Answer 5

You find
\[
\left\{a= 3,b=
\frac{1}{2}\right\}
\]

Answer 6

how do you solve the individual problems. Im confused on that part

Answer 7

find a from the first equation, then find a from the second equation, then find b.
After b, you can find a

Answer 8

so i got a=3, how do i right that in an exponential function

Answer 9

\[
a=24 b^3=12 b^2 \implies 2 b =1 \implies b=\frac 1 2\\
a = 12 (1/2)^2=3
\]

Answer 10

Thanks a lot. :)
