Use a graphing calculator to determine the linear, quadratic, or exponential equation that best represents the data. For linear and quadratics, round slope, -intercept, and coefficients to the nearest integer. For exponential, round to the nearest integer and to the nearest tenth.

Answer:

[tex]y=-13.5(x-1)^{\frac{2}{e}} +47[/tex]

Step-by-step explanation:

(29-47)/(2-1) = m₁ = -18

plot points:

(1, 47), (2, 29), (3, 20), (4, 10), (5,7), (6,5), (7, 1.5)

(See 1st attached)

(20-29)/(3-2) = m₂ = -9    (-18+(-9))/2 = -13.5

y=-13.5(x-x₁)^(2/e)+y(x₁)   x₁=1 (starting value)

y= -13.5(x-1)^(2/e)+47

1) Use this online graphing calculator if you do not have on ^^

2) plug in data and choose "e-Exponential regression"

3) A= 88.4385965

    B= -0.532128051

4) Round A to the nearest integer and B to the nearest tenth

5) Use the formula given "y=Ae^ Bx"

6) Leave the variables "e" and "x" as they are
