Question 17 • Algebra 2 with Probability

Which is the graph of f of x is equal to square root of x ?

Answer

A

Image with description On a coordinate plane, an absolute value graph starts at (0, 0) and goes up through (2, 4).

B

Image with description On a coordinate plane, a parabola opens up with a vertex at (0, 0).

C

Image with description On a coordinate plane, a parabola opens to the right with a vertex at (0, 0).

D

Image with description On a coordinate plane, an absolute value graph starts at (0, 0) and goes up through (4, 2).

Explanation

For f(x) = √x, the graph begins at (0, 0) and only exists for x ≥ 0. It passes through (4, 2), since √4 = 2, and curves upward while flattening out. Choice A describes this graph; the other choices show absolute value or parabolic graphs.
