It is y >= 5.
It is a quadratic function which represents a parabola.
The domain is from negative infinity to positive infinity. The range is from positive 2 to positive infinity.
No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
put it into the quadratic formula: for ax2+bx+c=0 x= - b (plus or minus)rad(b2-4ac) 2a

With difficulty because the discriminant of the quadratic equation is less than zero meaning it has no solutions

A quadratic function is a function where a variable is raised to the second degree (2). Examples would be x2, or for more complexity, 2x2+4x+16. The quadratic formula is a way of finding the roots of a quadratic function, or where the parabola crosses the x-axis. There are many ways of finding roots, but the quadratic formula will always work for any quadratic function. In the form ax2+bx+c, the Quadratic Formula looks like this: x=-b±√b2-4ac _________ 2a The plus-minus means that there can 2 solutions.
-2x2 + 9x - 12 = 0Then apply the quadratic formula.

The function is a simple linear function and so its nature does not limit the domain or range in any way. So the domain and range can be the whole of the real numbers. If the domain is a proper subset of that then the range must be defined accordingly. Similarly, if the range is known then the appropriate domain needs to be defined.
All that can be said is that F(x) is a quadratic function of x, with two real roots.
This is a basic quadratic function. The easiest way to go about this is by using the quadratic formula.a=5 ; b=20 ; c=20-b + or - root (b2-4ac) all over 2a.
x2+6x-7 = (x+7)(x-1) when factored
The range is y >= 5.
