Question 1195079: 3. You are being given a quadratic function in standard form, which is y = 2x2 - 26x + 72
a) Find the zeros (x-intercepts) of this function.
b) Write the equation of this quadratic function in factored form.
c) Write the equation of its axis of symmetry.
d) Find the optimal value of this function.
e) Write the equation of this quadratic function in vertex form.
4. An engineer needs to design a square-based berm ( a shallow container to prevent the spread of oil from a leaking oil tank). The cylindrical oil tank is 15 m in diameter, and has a height of 25 m. The berm must have a height of 4 m. Make the appropriate calculations and find the minimum dimensions of the berm.

----------------the answer for part (b)
Zeros at x for 4 and for 9.
Symmetry axis will be at the vertical line, .
You can use this to find the vertex point.
