Question

Use the graphing calculator to graph the function f(x) = StartRoot x EndRoot. Which table of values contains points that lie on the graph of the function?

A 2-column table has 4 rows. The first column is labeled x with entries negative 1, 0, 1, 4. The second column is labeled f (x) with entries 1, 0, 1, 16.

Answer 1

Choice C.

Explanation: sqrt(x) is undefined for x = -1, and sqrt(0)=0, sqrt(1)=1, sqrt(4)=2, so the table (undefined, 0, 1, 2) matches.
