Question 248159: given a quadratic equation in standard form y=ax^2+bx+c, explain what the coefficient of x^2 tells you

Positive coefficient "a" means the curve opens upwards (like a cup sitting on a table).
Large absolute value of a means "skinnier" graph compared to x^2 (green graph a=10).
Small absolute value of "a" means "wider" graph compared to x^2 (blue graph a=0.1).

Negative coefficient "a" means the curve opens downwards.
