For a compound function like that,, figure the innermost one out first, then use that value and move outwards

-4? or 4?
DanJS
  • DanJS
j(x) = -2x j(2) = -2 * 2 = -4
DanJS
  • DanJS
Now to calculate h[j(2)] ... you use that value for j(2), for x in h
DanJS
  • DanJS
h( - 4) = ...

Yay! I got it right (Sort of) and how would you find h(-4)

^ @DanJS

if h(x) = 5x-3 then h(-4) = 5*(-4) -3 = -20 - 3 = -23

for those, work the inner function first, then keep using those output values and work outwards to the next function like we did

  • DanJS
that is it, you figured the inner function out, which was -4, then you use that value in the outer function h(-4) that is it
