5-63.

Sketch the graph of *y* + 3 = 2* ^{x}*. 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?
