(a) Explanation Given: The function is, f ( x ) = x 2 − x . The points are x = − 2 and x = 1 . Formula used: Point-Slope Form : “If a line has slope m and passes through the point ( x 1 , y 1 ) , then an equation of the line is given by y − y 1 = m ( x − x 1 ) , the point-slope form of the equation of a line”. Slope of the secant line : The slope of the secant line can be obtained through the average rate of change formula. The average rate of change for the function f in the interval [ a , b ] is, f ( b ) − f ( a ) b − a . Calculation: Substitute x = − 2 in f ( x ) = x 2 − x to compute the value of f ( − 2 ) , f ( − 2 ) = ( − 2 ) 2 − ( − 2 ) = 4 + 2 = 6 Substitute x = 1 in f ( x ) = x 2 − x to compute the value of f ( 1 ) , f ( 1 ) = 1 2 − 1 = 1 − 1 = 0 Substitute a = − 2 and b = 1 in the formula (b) To determine To find: The equation of the tangent line at x = − 2 .
