ViviThe range of a function when you consider a graph is how high and how low it goes. A quadratic function is usually an arch that goes up to a high point and then back down like the arch of a kicked ball.
Or, it can be the reverse which goes down and then up in a mirror image of a kicked ball.
The range is what y values would be needed to show ALL the graph.
Example;
y=x^2+5x-6
The graph crosses the x axis at -5 and 1 it goes down then back up.
The range is from infinity down to -49/4

When can a quadratic function have an inverse?
It depends on the domain and codomain. In complex numbers, that is, when the domain and codomain are both C, every quadratic always has an inverse.If the range of the quadratic in the form ax2 + bx + c = 0 is the set of real numbers, R, then the function has an inverse if(a) b2 - 4ac ≥ 0and(b) the range of the inverse is defined as x ≥ 0 or x ≤ 0
What is the definition of a Vertex form of a quadratic function?
it is a vertices's form of a function known as Quadratic
What makes a function have a graph that is quadratic?
That the function is a quadratic expression.
What is the difference between a linear and quadratic function?
A linear function is a line where a quadratic function is a curve. In general, y=mx+b is linear and y=ax^2+bx+c is quadratic.
Is quadratic sequence exponential function?
No. It is a sequence for which the rule is a quadratic expression.
