This is the long way:
x2 + 16 = 0
x1= -1/2 + squareroot of -15,75
x2 = -1/2 - sqareroot of - 15,75
Note: squareroot of 16,25 is roughly ~ 4,03112575
Well, so much for the theory, but this question does not have any solution, since you can't draw the squareroot of a negative number like - 15,75.
And the short way:
x2 + 16 = 0
x2 = -16
x = squareroot of - 16, which as I declared above, is not possible.
Woops, I misunderstood your question; heres the answer to your question:
f(x) = x2 + 16
derivate
f'(x) = 2x
f'(0) = 2(0) Put in x = 0
f'(0) = 0 When x = 0, the curve turns and you have a minimi point.
f(0) = x2 + 16 Put in x = 0 in the first equation to get y.
f(0) = 02 + 16
f(0) = 16 y = 16
minimum point: x = 0, y = 16 --> (0;16)

What graph could be used to find the solution of the system of equations y equals 2x plus 6 and y equals x2 plus 4x plus 3?
A graph that has 1 parabolla that has a minimum and 1 positive line.
What is the maximum or minimum value of y equals x to the power of 2 minus 4x plus 7?
It has an absolute minimum at the point (2,3). It has no maximum but the ends of the graph both approach infinity.
What is the vertex of the parabola when y equals 3x squared plus 2x minus 1?
The minimum value of the parabola is at the point (-1/3, -4/3)

What is the vertex of the parabola y equals x2 plus 8x plus 5?
The vertex has a minimum value of (-4, -11)
What are the coordinates of the minimum point of a porabola whose equation is y equals x squared plus three?
y = x2 + 3 Since the x term is missing, the x-coordinate of the vertex is 0. If x = 0, then y = 3. Thus, (0, 3) is the vertex, the minimum point of the parabola.
How do you make a cross symbol on your keyboard?
you have to find the key with the plus and equals symbol. Then push the shift key and the plus/equals key. The "cross" should show up. Plus (+) equals (=). The plus should be above the equals.
What is the common point of these equations x plus 2y equals 6 x plus y equals 2?
When x = -2 then y = 4 which is the common point of intersection of the two equations.
If ac plus cb equals ab and ac equals cb then the point c is?
the midpoint of AB.
