Question

The function g(x) = 10x2 – 100x + 213 written in vertex form is g(x) = 10(x – 5)2 – 37. Which statements are true about g(x)? Select three options. The axis of symmetry is the line x = –5. The vertex of the graph is (5, –37). The parabola has a minimum. The parabola opens up. The value of a, when the equation is written in vertex form, is negative.

Answer 1

Answer:

• The vertex of the graph is (5, -37) [see attached image]
• The parabola has a minimum [the coefficient of x² is positive]
• The parabola opens up [the coefficient of x² is positive]
