Use the function below to answer parts a and b. f ( x ) = 7 x x 2 + 1 Calculate the local extrema. Enter answers in decimal format (no fractions). The local min is : ([BLANK-1], [BLANK-2]) The local max is: ([BLANK-3],[BLANK-4]) b. Identify the intervals on which the function is increasing and decreasing. The interval(s) on which f ( x ) is increasing is/are [BLANK-5]. The interval(s) on which f ( x ) is decreasing is/are [BLANK-6] NOTE: YOU MUST USE THE EQUATION TOOL TO ENTER YOUR INTERVALS. Separate multiple intervals with a comma and use -infinity to represent – ∞ and infinity to represent ∞ .

Use the following equation to answer parts a and b.3xy2+3x-y=1 a. Implicitly differentiate the equation above. (Answer should be of the form y’=_____) b. Write the equation of the tangent line through (1,1). You may write the equation in point-slope form (y-y1=m(x-x1)or slope-intercept form (y=mx+b).NOTE: YOU MUST USE THE EQUATION TOOL FOR BOTH PARTS. SEPARATE THE TWO ANSWERS WITH A SEMICOLON (;).
