Sketch the graph of y + 3 = 2x. Homework Help ✎
What are the domain and range of this function?
Does this function have a line of symmetry? If so, what is it?
What are the x- and y-intercepts?
Change the equation so that the graph of the new equation has no x-intercepts.
Domain: all real numbers
Range: y >−3
There is no line of symmetry.
(0,−2) and (1.585, 0)
What is the value in the original equation that causes it to have an x-intercept?
How can you change it so that the new equation will not have an x-intercept?
