  2. 2 M th znan • zaidi A function f is defined by f(x) = x2 — 2.r + 5 for x e R. A sequence Of transformations is applied in the following order to the graph of y = f(x) to give the graph of y = g(x). Stretch parallel to the x-axis with scale factor 2 VReflection in the y-axis Stretch parallel to the y-axis with scale factor 3 Find g(x), giving your answer in the form ax2 + bx + c, where a, b and c are constants. l_te__ 5 (Cam) 34(-aÖ = [41
  3. Functions f and g are both defined for x e R and are given by f(x) = — 9, (a) Express f(x) in the form (x — + b. (b) Express g(x) in the form + + d]. [2] Math Bender by Adnen Zaidi
  4. (c) Express g(x) in the form kf(x + h), where k and h are integers. TO (d) Describe fully the two transformations that have been combined to transform the graph to the graph of y = g(x). evulleL to [4] Math Bender by Adnen Zaidi
