Look at the chart showing a clothing stores daily stock data for the past month . Which statement is a fair conclusion based on the chart

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

This is so hard and it’s for a test

For what values of x is x2 + 2x = 24 true?
