The graph crosses the x axis  where  g(x) = 0 , so:-

x^2 - 5 = 0
x^2 = 5
x =  sqrt5 or -sqrt5

so grapg corosses the x axis at (-sqrt5,0) and (sqrt5, 0)

What is the best estimate for the length of a bike
castortr0y [4]
<span>The average length of a bike (including the length of both wheels) is about 68 inches.For finding the true answer we must follow the following convertion rule: 1 inch is equivalent to 0.02 yard, so 68 inches equal to 1.88 yards. Consequently, the value nearest 1.88 yards is 1.5 yards, so the answer is the choice A: 1.5 yards. </span>
