Finding specific quadratic function values
WebJan 31, 2016 · Now solving for x in terms of y using the quadratic formula gives: x = − b ± b 2 − 4 a ( c − y) 2 a This will have a solution as long as b 2 − 4 a ( c − y) ≥ 0 You can rearrange this inequality to get the maximum value of y in terms of a, b, c. See if you get the same answer as the calculus approach gives. WebOct 6, 2024 · f(x) = a(x − h)2 + k You will quickly learn that the graph of the quadratic function is shaped like a "U" and is called a parabola. The form of the quadratic function in Equation 5.1.1 is called vertex form, so named because the form easily reveals the vertex or “turning point” of the parabola.
