Use the exponential regression feature of the desmos graphing calculator to create an exponential equation for the following data. Round the 'a' value to the NEAREST WHOLE NUMBER and the 'b' value to THREE DECIMAL PLACES. Enter your equation like one of these examples: y=5(1.789)^x; y=342(0.571)^x DO NOT USE THE COMMA WHEN ENTERING 10000.00 INTO DESMOS.

Consider the function f left parenthesis x right parenthesis equals 4 x squared minus 3 x minus 1f(x)=4x2−3x−1 and complete parts (a) through (c). (a) find f left parenthesis a plus h right parenthesis f(a+h); (b) find startfraction f left parenthesis a plus h right parenthesis minus f left parenthesis a right parenthesis over h endfraction f(a+h)−f(a) h; (c) find the instantaneous rate of change of f when aequals=77.
