The graph of the quadratic function f(x) = c +bx − x^2 intersects the -axis at point A(−1, 0) and has its vertex at point B(3, 16) Write down the equation of the axis of symmetry for this graph.

Find the value of b.

i) Write down the range of (x).
ii) g(x) is the function f(x) on the restricted domain x < 3. Find g-1(x), stating the domain
and range of this function.

Players on the school soccer team are selling candles to raise money for an upcoming trip. each player has 24 candles to sell. if a player sells 4 candles a profit of$30 is made. if he sells 12 candles a profit of $70 is made. determine an equation to model his situation?

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
