Question

what is the domain and range for y=x2-6x+5

x should be x square

Answer 1

the domain is all real numbers
the range is -5 to infinity.

Answer 2

could you show me how you get the answer

Answer 3

To know about the domain.. one of the givens are that this equation is a polynomial, its x^2-6x+5. So all polynomials have a domain that consists of all real numbers.

Answer 4

to find range plot the graph. If you don't know how to do it correctly or well, then you first should solve the equation to find where the graph touches x axis. so it would be
(x-5)(x-1)(equal them to zero). here u see that the graph touches x axis at x=1,5. since this equation is a parabola, then this is the interval in which goes to bottom and back to the top, plug in points from 1-5 to see the lowest point (y). And since its a parabola it will go on to infinite
