Question

Select the correct answer. This graph represents a quadratic function. An upward parabola on a coordinate plane vertex at (minus 2, 2) and passes through (minus 3, 5) and (minus 1, 5). What is the value of a in the function’s equation? A. 2 B. -3 C. -2 D. 3

1. thaiduong
y = 3x^2 + 12x + 14 is the equation of a parabola whose vertex is located at (-2, 2) and which also traverses the points (-3, 5) and (-1, 5). In the equation, the value of an is 3, and it is a constant.

### What exactly is an equation, then?

An expression known as an equation is one that illustrates a connection between two or more sets of numbers and variables.
A quadratic equation will produce a graph that looks like a parabola because of its form. The typical form of the quadratic equation is as follows:
y = ax² + bx + c
y = 3×2 + 12x + 14 is the equation of a parabola whose vertex is located at (-2, 2) and which also traverses the points (-3, 5) and (-1, 5). In the equation, the value of an is 3, and it is a constant.
