Complex numbers

Enter the data for Spendco into your graphing calculator. Enter the years since 2000 as the x-values and the corresponding daily hits in thousands as the y-values. a. To find the exponential equation that models the data, use the exponential regression feature of your calculator. The calculator should return values for a and b. Write these values below, rounding to the nearest hundredth. a= b. Write the exponential equation in the form $$\displaystyle{y}={a}{b}^{{x}}$$.
c. Use the exponential equation to predict the number of daily hits for Spendco in 2015.

a. Values using the graphing calculator $$\displaystyle{a}={2.00396}→{2.00}$$
$$\displaystyle{b}={1.79956}→{1.8}$$
b. Exponential Equation $$\displaystyle{y}={\left({2.0}\right)}{\left({1.8}\right)}^{{x}}$$
c. Daily hits of Spendco in 2015
x=2015-2000=15 value of x
$$\displaystyle{y}={\left({2.0}\right)}{\left({1.8}\right)}^{{x}}$$ substitute the value of x
$$\displaystyle{y}={\left({2.0}\right)}{\left({1.8}\right)}^{{15}}$$ exponent rule
y=(2.0)(6764.64) multiplication
y=13493.28 daily hits for Spendco in 2015
