8 The table below shows some values of x and the corresponding values of y for y=1/4×2^x . (a) Complete the table. (b) On the grid below, draw the graph of y=1/4×2^x . (c) By drawing a suitable line, find the gradient of your graph where x = 4. (d) (i) Show that the line 2x + y = 6 , together with the graph of y=1/4×2^x , can be used to solve the equation 2^x + 8x − 24 = 0 . (ii) Hence solve 2^x + 8x − 24 = 0 . (e) The points P and Q are (2, 3) and (5, 4) respectively. (i) Find the gradient of PQ . (ii) On the grid, draw the line l, parallel to PQ, that touches the curve y=1/4×2^x. (iii) Write down the equation of l.
