A girl's height h(t) (in centimeters) is measured at time t (in years) for O < t < 14: - - 52, 75.1, 87.5, 96.7, 104.5, 111.8, 118.7, 125.2, 131.5, 137.5, 143.3, 149.2, 155.3, 160.8, 164.7 (a) What is the average growth rate over the 14-yr period? (b) Is the average growth rate larger over the first half or the second half of this period? (c) Estimate h1 (t) (in cm/yr) fort = 3, 8.
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
