HELP algebra 1 work!
Complete the chart and determine the solution of the equation f(x) = g(x)
f(x) = 2x + 24 g(x) = 5(0.5)x
but none of the choices work which are: x = -2 x = -1 x = 1 x = 20
@paki help?
@midhun.madhu1987 help?
@Sheraz12345 please help...
i think the quistion is wrong but im not sure!
wait what are the 2 equations..
theyre f(x) = 2x + 24 g(x) = 5(0.5)x
set the 2 equations equal to each other
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
OOOOOOOO
Hence the g(x) = f(x), think of it as 20 = 20
wait what?
now im lost how is it -2?
graph the 2 equations and see the x value of where it intersects
yep its -2
also i replaced x with -2 and it was 20=20
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.
