3. Therefore, the options 1), 3) and 4) have equal volumes.
Using the vertex of the equation, it is found that the correct option regarding the minimum number is given by:
C. n = 2(t - 2)² + 7.
<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.
Considering a standard equation, given by:
y = ax² + bx + c.
The vertex is given by:
.
If a is positive, the vertex is a minimum value.
In this problem, the equation is given by:
n = 2t² - 8t + 15.
The coefficients are: a = 2, b = -8, c = 15.
Hence:
.
The minimum is 2 hours after 10 a.m., hence 12 p.m, and the function is:
C. n = 2(t - 2)² + 7.
