Show algebraically that f and g are inverse functions f(x)=x^2/-6; g(x)=square root of 2x+12

(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.

What is the reflection image of (5,-3) across the line y = -x?
