ran throught a cal is
Step-by-step explanation:
Slope (m) =
ΔY
/ΔX
=1/3
=0.33333333333333
373-13=360
360 divided by three equal to 120
So 120 children chose basketball
15% each yer
represented by
f(x)=60(1.15^x)
xintercept is when the function equals zero
since it increases only, it cannot equal zero and does not have an x intercept
after 4 years the investment value is 104
after 6 yaers value is 138.7
after 7.86 years the value is179.98 which is roughly 3 times of 60
8 years later183.54 close enough
answers
f(x)=60*1.15^x
after 7.86 years value is 3 times initioal value
after 8 years value is 184
