The answer is 7 teaspoons for one cup
This is a parabola, meaning the equation is a quadratic, so it has 2 roots or x-intercepts, keeping in mind that vertex will lie half-way between those intercepts.
so what's the x-value halfway between -3 and 7? yeap, you guessed it, 2.
so the axis of symmetry for this vertical parabola will be at x = 2.
Algebra
The formula to find the coordinate is (x,y)
Meaning, point D is (1,4)
