Need help with question 2 please

(a ) If P(L) = LAK + HOK evaluate P(3), P(K5), P ( VH ) , P (VHK) ( b) If T(K ) = LAK + H2K 12 evaluate T(3), T( 15 ) , T ( VH ) , T ( VAL ) 2. If g( u ) 1xy ( cuz + but a ) 3 yu write g(u) = f(h(u)) for appropriately chosen f(u) and h(u) (where you are not allowed to use f(u) = u as one of the function choices for f). Note that u, not x nor y is the independent variable. 3. (a) If f(x) = 25 and m(x) is obtained from f (x) by shifting f(x) 2 units to the left and 9 units up, then scaling vertically by multiplying by a factor of 4, what is the formula for m(x)? (b) If f( 2) = 25+ 2x and m(x) is obtained from f(x) by shifting f(x) 2 units to the right and 9 units down, then scaling horizontally by multiplying by a factor of 7, what is the formula for m(x)? 4. If f(x) =Vx and g(x) is obtained from f(x) by reflecting f (x) about the y axis, and shifting right by 2 units and then shifting up by 1 unit? Sketch this graph using 3 test points and state the formula for g(x) 5. Simplify the following. Very Important: You need to be able to do such problems without a calculator. ADVICE: DO NOT USE YOUR CALCULATOR. (128) 2/7 K8/7 L-5/6 p14/11 + K-6/7 17/6 p-8/11 (a) 32-4/5 (b) ( c) 6 K1/7L1/6 p3/11 6. (a) Solve 3xz - Bx = 10z for z; (b) Solve 3xz - 3x = 10z for x; (c) Solve 1 5 for 0. Write your answer as a fraction simplified as much as possible. 20 63 7. Find an equation of the line through the points (b, 7c) and (46, 10c), where b * 0
