Introduction to Quadratic Functions Answers

Which represents a quadratic function?

When simplified and written in standard form, which quadratic function is equivalent to the polynomial shown?2 + 7c – 4c2 – 3c + 4

A 2-column table with 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f of x with entries 21, 10, 5, 6, 13.

liana started to evaluate the function f(x) = 2x2 – 3x + 7 for the input value 2.f(x) = 2(2)2 – 3(2) + 7 = 2(4) – 3(2) + 7

Consider the quadratic function f(x)=8x2−7x+6. What is the constant of the function?

Which equation represents a quadratic function with a leading coefficient of 2 and a constant term of –3?

On a coordinate plane, a parabola opens up. It goes through (negative 7.5, 4), has a vertex of (negative 3, negative 9), and goes through (1.5 4). Solid circles appear on the parabola at (negative 7, 1.75), (negative 6, negative 3), (negative 3, negative 9), (0, negative 3), (1, 1.75).

When the polynomial is written in standard form, what are the values of the leading coefficient and the constant?5x + 2 – 3x2
