F(x) = 3x² - 12
Finding where the graph crosses the axes will help us to determine the correct graph
When x = 0,
f(0) = 3(0)² - 12
f(0) = -12
So we have one point (0, -12)
When y = 0
0 = 3x² - 12
12 = 3x²
4 = x²
√4 = x
x = ⁺/₋ 2
So the graph crosses the x-axis at -2 and 2 and the y-axis at -12
The correct graph is option A

Not quite sure what you mean by brackets, but you can get the solution to this equation in a few steps:
<span>(-2x - 1)</span>² <span>= 0 ... square root both sides to eliminate the squared binomial
</span>√(-2x - 1)² = √0 ... simplify; the square is canceled out and the root of 0 brings you back to 0
-2x - 1 = 0 ... solve like a two-step equation
-2x = 1
x = -1/2 is your x-value.
