Answer:
f(x) = 18,000 • 0.85^x
Step-by-step explanation:
30*4=120 not 129
So if we use a calculator the correct answer is 32 1/4
So Kalinda starts with $25. Then she spends $14.28. This means you subtract since she spends it. Next, she shares $2.65. Again, use subtraction. The remainder is your answer. Or you can add 14.28 to 2.65 and then subtract that from 25.
OK. Instead of trying to find a quick, slick, easy, short way,
let's just do it the long, sensible way. We'll find the value of
each function at x=-2 and at x=-4, then see which one changed
the most and which one changed the least.
g(x) . . . (table)
when x=-2 . . . g(x) = 0
when x=-4 . . . g(x) = -8
Amount of change . . . 8
h(x) = |2x + 3| + 7
h(-2) = |-4+3| + 7 = 1+7 = 8
h(-4) = |-8+3| + 7 = 5+7 = 12
Amount of change . . . . . . . 4
m(x) . . . (graph)
m(-2) . . . . . -10
m(-4) . . . . . less than -18
maybe -20 or -25
Amount of change . . . more than 8
maybe 10 or 15
Largest change . . . m(x)
Smallest change . . h(x)
