How do you graph #y=sqrtx+3# and compare it to the parent graph?

Answer 1

Try different x values to find y.

It is first defined on the plus side (for x).

For x=0, your function #y=4# For x=2, your function #y=4.41# For x=3, your function #y=4.73# For x=4, your function #y=5# etc. and then plot it.

This is it:

graph{(sqrtx)+3 [ 1.62, 8.38, 17.745, -2.255]}

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
