Question 90016: How are the zeros for a function (the values that make the function value equal zero), and the x-intercepts for the graph of the function related to each other?
A quadratic function has a definite maximum or minimum point (its vertex) that other polynomials may not have. This makes it a good candidate for use in application problems that may require finding a maximum or minimum quantity. If A(x) = -6x2 + 2x + 3 is used to describe a situation involving Area, or Altitude, or Age. How would you go about using the function and its graph to determine the maximum area, altitude or age?
Please explain!!!!

Question 90218: I need to identify the axis of symmetry, create a suitable table of values and the sketch a graph including the axis of symmetry for y = x^2 - 5x + 3.
I know the formula to find the axis is x = -b/2(a)thus...
x = -(-5)/2(1) = 5/2
From here on out I'm lost. I get really confused when there is a fraction. I don't which values to choose and why to choose them.
Please help.

Question 90223: I need to identify the axis of symmetry, create a suitable table of values and sketch a graph including the axis of symmetry for: y = x^2 - 5x +3
I know the formula to find the axis is x = -b/2a thus
x = -(-5)/2(1) = 5/2
From here on out I'm lost. I get really confused whenever fractions are involved. I'm not sure what numbers to choose for my values and why to choose those numbers.
Any help would be appreciate.

Question 90259: Solve each of the following systems by addition. If a unique solution does not exist, state whether the system is inconsistent or dependent. Problem 12 is reminiscent of Examples 1, 2 and 3 (pp 690-692) and Problem 20 is much like Example 4 (p 693)
12) 2x + 3y = 1
5x + 3y = 16
20) x + 5y = 10
-2x – 10y = -20
