can someone please tell me how to plot graphs such as 2x^2 + 10 or something like that cause to be honest it is one my major weaknessess at maths... lol
step one determine where the equation crosses the y-axis (when x=0)
step two determine where the equation crosses the x-axis (when y=0)
, it does not cross the x-axis
Step three determine what shape the equation has
in this case the equation is a parabola that opens upward and is symmetric about the y-axis, therefore its minima is at (0,10)
Play around with a graphing calculator and see what happens to as A, B and C change.
