# How do you graph #f(x) = 3sqrtx + 2 #?

##### 1 Answer

You take a few critical points, and graph.

#### Explanation:

Normally we choose the Y-intercept (when x=0) and the X-intercept (when y=0), and x=1, x=-1, x=2, etc. Close values to zero.

Let's calculate the y-intercept first.

x=0

y-intercept

y=0

0=3

-2=3

x=1

3

x=-1

of a negative number does not exist.

Pretty soon we can see that the graph will start AFTER zero and nothing before. Then it will be a curve low to high as it progresses right. Graph below:
