How do you find square roots larger than 100 by hand?

1 answer:

6 0

Write out all the factors until you find two of the same number like 144’s factors are (1,2,3,6,8,9,12,12,16,18,24,48,72,144) so the root is 12 it takes a long time but that’s how i do it‍♀️

Graph each absolute value function. State the domain, range, and y-intercept.

Answer:

The domain is $(-\infty,\infty)$ and its range is $[3,\infty).$

The y-intercept is (0,3).

Step-by-step explanation:

Consider the parent function $y=|x|.$ Its domain is $x\in (-\infty,\infty)$ and its range is $y\in [0,\infty).$

The graph of the function $y=|x|+3$ is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the domain and will change the range of the function, thus the domain is $(-\infty,\infty)$ and its range is $[3,\infty).$
