What is a line graph and bar graph?
A line graph is shaped like a triangle and a bar graph is exactly like column but bar graph is other way around
How many graphs are there?
Infinitely many. There is a different shaped graph for each function that can exist. Plus there are graphs for non-functional measures. One of my favourites is Minard's graph depicting the losses sustained by Napoleon's army in Russia. See link.
Why is a pie graph called a pie graph?
I'm guessing because it has nothing to do with 3.14, it's because it is shaped like a pie!
How do a and c affect a quadratic graph?
Assuming a nd c refer to the coefficients in y = ax2 + bx + c Then, if a>0 the graph is cup (U) shaped whereas if a<0 the graph is cap shaped. c determines how high or low (above or below) the x-axis sits and, therefore, whether or not the quadratic has real roots.
What is meant by the maximum and minimum values of qadratic equation?
A quadratic can be drawn as a graph and it is either "U" shaped or "n" shaped. If it were "U" shaped, the minimum value qould be the lowest point of the "U". If "n" shaped, maximum would be the top.
