For this , you use the distance formula
. based on the graph, use points (0,6) and (7,-2), plug them into the formula to get
and you get B, 10.63
It's just asking for the gradient basically
150/3 = 50
Or technically -50 because it's decreasing
Comparing to the standard equation, the parabola with a vertex at (-2,0) is given by:
y = (x + 2)²
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
In this problem, we have that h = -2 and k = 0, and all the options have leading coefficient a = 1, hence the equation is:
y = (x + 2)²
