A ball is thrown into the air. The table shows the heights h (in feet) of the ball after t seconds. Write a function that models the height of the ball over time. You may use
DESMOS, the regression feature of your calculator to find the model that best fits the
data.
Time, t: 0,2,4,6
Height, h: 3,19,19,3

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
