Use the graph to evaluate the expression.Find (f + g)(-3) and (f - g)(-1).
A. (f + g)(-3) = -1; (f - g)(-1) = 1 B. (f + g)(-3) = 29; (f - g)(-1) = 17 C. (f + g)(-3) = -1; (f - g)(-1) = 3 D. (f + g)(-3) = -11; (f - g)(-1) = -15
Solve the problem.A survey of the interest rates earned by Certificates of Deposit (CDs) showed the following percents for the length of time (in years) for holding the CD. Let length of time represent the independent variable and interest rate represent the dependent variable. Use a graphing utility to draw a scatter diagram and to find the line of best fit. What is the estimate of the interest rate for a CD held for 30 years (to the nearest thousandth)?
