The square root of 24 would be plotted between 4 and 5, but closer to 5 on a number line.
<h3>What is a number line?</h3>A number line is a horizontal line with evenly spaced numerical increments. The numbers on the line will dictate how you answer the number on the line.
A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, denoted by \mathbb {R}. Every point on a number line is assumed to be a real number, and every real number is assumed to be a point.
Number lines are extremely adaptable, that can be used to locate numbers, compare numbers, fractions and mixed numbers, decimals, integers, absolute value, addition, subtraction, inequalities, multiples, common denominators, and much more.

They intercept in two points.
The graph y=x^2 is very basic so I suppose you know how it looks like.
It's like a U and starts from the origin (0,0)
The graph y=cosx is similar to y=x^2 but in a different way.
y=cosx doesn't pass from (0,0) it passes from (0,1) and then to (-1,0) and (1,0).
Basically, it goes like this..

If you know how the two graphs look like then you can understand why they intercept only two times.
