A) For the following function, use the given set of intervals to estimate the slope of the tangent line of the function at x=−2 x 2 by producing the slopes of the secant lines that pass through the x x-values of each of the intervals. f(x)=2x2+1;[−4,−2],[−3,−2],[−2.5,−2 ],[−2.25−2] b) For the following function, use the given set of intervals to estimate the slope of the tangent line of the function at x=6x6by producing the slopes of the secant lines that pass through the xx-values of each of the intervals.
f(x)=3x2;[6,8],[6,7],[6,6.5],[6,6.2 5]
