<h2>The graph of y = ax^2 + bx + c
</h2><h2>A nonlinear function that can be written on the standard form
</h2><h2>ax2+bx+c,where a≠0
</h2><h2>All quadratic functions has a U-shaped graph called a parabola. The parent quadratic function is
</h2><h2>
y=x2
</h2><h2>
The lowest or the highest point on a parabola is called the vertex. The vertex has the x-coordinate
</h2><h2>x=−b2a
</h2><h2>The y-coordinate of the vertex is the maximum or minimum value of the function.
</h2><h2>a > 0                   parabola opens up                    minimum value
</h2><h2>a < 0                    parabola opens down              maximum value
</h2><h2>
A rule of thumb reminds us that when we have a positive symbol before x2 we get a happy expression on the graph and a negative symbol renders a sad expression.
</h2><h2>The vertical line that passes through the vertex and divides the parabola in two is called the axis of symmetry. The axis of symmetry has the equation
</h2><h2>x=−b2a
</h2><h2>The y-intercept of the equation is c.
</h2><h2>
When you want to graph a quadratic function you begin by making a table of values for some values of your function and then plot those values in a coordinate plane and draw a smooth curve through the points.</h2>
        
             
        
        
        
If a polynomial has more than one variable, then thedegree<span> of that </span>monomial<span> is the sum of the exponents of those variables. In this polynomial, 24xyz, the</span>degree<span> is 3 because the sum of </span>degrees<span> of x, y and z is 1 + 1 + 1 = 3. hope this helps :)</span>
        
             
        
        
        
The javelin will hit the ground 14.66 or 15 seconds upon Maria's release from the said distance. The computation are as follows: 
time = distance/speed (d/m)
time = 22 meters/second / 1.5 meters 
time = 14.66 seconds or 15 seconds
