Domain And Range Of A Negative Parabola
Domain and range of a parabola opening down the down parabola the one in black opens down and moves infinitely along the negative y axis and has the vertex at 10 10.
Domain and range of a negative parabola. So our domain but it can take on all the vaues. Given a quadratic function find the domain and range. And we know that our vertex is at a point 5 2s and 1 4.
Infinity infinity range in interval notation. Looking at the graph from learnzillion created by emily eddy standards. The general form of this equation would be y ax 2 bx c we observe that the sign of the leading coefficient a is negative.
So our range so we already said our domain is all real numbers. Determine the domain and range of a parabola. Although the range is easy to find i d rather play safe and graph it again.
Y 4 would be included in the domain but y 4 would not be included. So the parabola can never give you values f of x is never going to be less than negative 5. The domain of any quadratic function as all real numbers.
Range of a quadratic function the graph of the parabola has a minima at y 3 and it can have values higher than that. So what we end up is our range being from negative 1 4 to infinity. The domain should be all x values because there are no values that when substituted to the function will yield bad results.
Y 2 domain in interval notation. Which means our parabola is going to be facing upwards. Determine the domain and range of a parabola.
