Theo compared 7/10 and 1/3 by first comparing each fraction to 1/2 Step 1: 7/10 is less then 1/2

Step 2: 1/3 is less then 1/2

Step 3: 7/10 > 1/3

In which step did Theo make his first mistake

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.
