The statement which is true are f(x)​ and ​g(x)​ have a common x-intercept (B) and the maximum value of ​g(x)​ is greater than the maximum value of ​f(x)​ (C).
What is x-intercept?
The x-intercept is the point on the coordinate at which a line, curve or plane intersect with the x-axis. The value of y is equal to zero at x-intercept.
The function f(x) shown in the graph has two x intercept (5,0) and (1,0). The x intercept of g(x) are (-3, 0) and (5, 0).
Similarly, the y-intercept is the point on the coordinate at which a line, curve or plane intersect with the y-axis. The value of x is equal to zero at y-intercept.
The function f(x) shown in the graph has one y intercept (0,-1). The y intercept of g(x) is (0, 3). Here the maximum value of f(x) is 2 while g(x) is 4.
Thus, the statement which is true are f(x)​ and ​g(x)​ have a common x-intercept (B) and the maximum value of ​g(x)​ is greater than the maximum value of ​f(x)​ (C).
