Question

anonymous · Answer

Complete the chart and determine the solution of the equation f(x) = g(x)

anonymous · Answer

f(x) = 2x + 24
g(x) = 5(0.5)x

anonymous · Answer

but none of the choices work which are: 
x = -2

 x = -1

 x = 1

 x = 20

anonymous · Answer

i think the quistion is wrong but im not sure!

anonymous · Answer

wait what are the 2 equations..

anonymous · Answer

theyre f(x) = 2x + 24
g(x) = 5(0.5)x

acxbox22 · Answer

set the 2 equations equal to each other

the_fizicx99 · Answer

Mmm, do you mean $\ \sf g(x) = 5(0.5)^x $ ? If so, because one is linear and one is exponential they intersect when both have the same value http://prntscr.com/4avcl7 therefore it's a x = -2

anonymous · Answer

OOOOOOOO

the_fizicx99 · Answer

Hence the g(x) = f(x), think of it as 20 = 20

anonymous · Answer

wait what?

anonymous · Answer

now im lost how is it -2?

acxbox22 · Answer

graph the 2 equations and see the x value of where it intersects

anonymous · Answer

yep its -2

anonymous · Answer

also i replaced x with -2 and it was 20=20

the_fizicx99 · Answer

20 = 20 is true, so you have to find what "x" coordinate these function have in common that will equal in the same y coordinate.
