Question

What is the line of symmetry for the parabola whose equation is y = 3x2 + 24x - 1?

Answer 1

The line of symmetry is -4

Answer 2

for a parabola in the form

\[y=ax^2 + bx + c\]

the line of symmetry is

\[x = \frac{-b}{2 \times a}\]

in your question a = 3 abd y = 24

substitute and calculate the answer

hope it helps

Answer 3

You get this answer from using the formula -b/2a, you plug in 24 and make it negative, then plug in a which is 3 and then get -24/6 and then finally all you do is simplify, which leads to -4
