All you're doing is replacing the x values with the ones given in the table
if x = 2, then what is the value of 2.5x - 10.5 ?
OpenStudy (celinegirl):
@jim_thompson5910 -5.5

Jim got this no worries.
jimthompson5910 (jim_thompson5910):
yes @celinegirl so -5.5 will go in the first row under the f(x) column

you'll do the same for x = 3 all the way up to x = 6 for f(x)
then repeat things for g(x)
OpenStudy (celinegirl):
@jim_thompson5910 aha okay
jimthompson5910 (jim_thompson5910):
let me know what you get
OpenStudy (celinegirl):
@jim_thompson5910 okay would it be: -3, -0.5, 2, 4.5
jimthompson5910 (jim_thompson5910):
yes, all for f(x)

@jim_thompson5910 okay thanks but do i do for the other?
jimthompson5910 (jim_thompson5910):
you'll do the same steps for g(x)
jimthompson5910 (jim_thompson5910):
if x = 2
g(x) = 64*(0.5^x)
g(2) = 64*(0.5^2)
g(2) = _____ (fill in the blank)
OpenStudy (celinegirl):
16? ehh @jim_thompson5910
jimthompson5910 (jim_thompson5910):

Aha okay and do that for the rest?
jimthompson5910 (jim_thompson5910):
correct
OpenStudy (celinegirl):
Not sure but.. 8, 4, 2, 1 @jim_thompson5910 ?
jimthompson5910 (jim_thompson5910):
yep
jimthompson5910 (jim_thompson5910):
look for the row where the value of f(x) is equal to the value of g(x)
what x value makes this possible?
