What is the x-intercept of the graph shown?

Back question 35 of 229 Next

Explanation

Choice D is correct. The x-intercept of the graph shown is the point x,y on the graph where y = 0 . At y = 0 , the corresponding value of x is 4 . Therefore, the x-intercept of the graph shown is 4,0.

Choice A is incorrect. This is the x-intercept of a graph in the xy-plane that intersects the x-axis at x = -5 , not x = 4 .

Choice B is incorrect. This is the x-intercept of a graph in the xy-plane that intersects the x-axis at x = 5 , not x = 4 .

Choice C is incorrect. This is the x-intercept of a graph in the xy-plane that intersects the x-axis at x = -4 , not x = 4 .
