it is a rational number (intergers are plus and minus whole numbers)
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

ANSWER:
Instead of greater than, the inequity symbol should be greater than or or equal to.
Step-by-step explanation:
We know the variable x represents the number of students. We also know there are 5 chaperones attending; this makes x+5 , by 2.50
It costs $2.50 per person; this means we multiply the number of people, x+5, by 2.50:
2.50(x+5)
The class has $90 to spend; this means they can spend up to and including $90. This gives us
90>2.50(x+5)

R u serious,
y=1/2x
graph at (0,0), and (10, 5)
