Document Summary
Point values for individual questions are given in parentheses following the question number. First, 3. 25% gives an interest rate expressed as a fraction of the initial value per annum, rather than a percent, of . 0325, so. = . 3 = 30: (20) correctly label each of the following functions as a power function, an expo- nential function, a linear function, or none of these. Exactly one of the functions is correctly labelled with two of the types of functions, label it with both correct types of function. Rewrite any power functions not already in the form k xp in that form. (a) f (x) = 2/ x = 2 x (b) g(x) = 3 2x exponential function. 2 power function (c) h(x) = 5x = 5 x1 power function and linear function (d) j(x) = 5x 2 linear function (e) (x) = 4. 5x1. 03 = . 80 x 1. 03 power function (f) m(x) = x2.
