The vertex of this parabola is at (3,-2). When the x-value is 4, the y-value is 3: (4,3) is a point on the parabola. Let's use the standard equation of a parabola in vertex form:

y-k = a(x-h)^2, where (h,k) is the vertex (here (3,-2)) and (x,y): (4,3) is another point on the parabola. Since (3,-2) is the lowest point of the parabola, and (4,3) is thus higher up, we know that the parabola opens up.

Substituting the given info into the equation y-k = a(x-h)^2, we get:

3-[-2] = a(4-3)^2, or 5 = a(1)^2. Thus, a = 5, and the equation of the parabola is

y+2 = 5(x-3)^2 The coefficient of the x^2 term is thus 5.

Answer:

<h2><u><em>(2s + 5) × (2s + 5)</em></u></h2><h2><u><em>or</em></u></h2><h2><u><em>(2s + 5)²</em></u></h2>

Step-by-step explanation:

A side of a square garden is represented by the expression 2s + 5. Which expression represents the area of the garden?

Area = s * s ( side x side or side²)

(2s + 5) * (2s + 5)

or

(2s + 5)²
