The diagram shows the graph of y = x/2 + 2/x, for 0 < x ≤ 8 (a) Use the graph to solve the equation

x/2 + 2/x = 3

(b) By drawing a suitable tangent, work out an estimate of the gradient of the graph where x = 1

Pleting the square f the given find the x-intercepts of the parabola with vertex (-5,13) and y-intercept (0, 12). write your answer in this form: (14,.99). if necessary, round to the nearest hundredth. *- h enter the correct answer, de verter, and ametry 00000 done doo
