(a) Explanation Given: The function is, f ( x ) = x 2 + 2 x . The point are x = 3 and x = 5 . 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 = 3 in f ( x ) = x 2 + 2 x to compute the value of f ( 3 ) , f ( 3 ) = 3 2 + 2 ( 3 ) = 9 + 6 = 15 Substitute x = 5 in f ( x ) = x 2 + 2 x to compute the value of f ( 5 ) , f ( 5 ) = 5 2 + 2 ( 5 ) = 25 + < (b) To determine To find: The equation of the tangent line at x = 3 .
