Remains in the tank of semi truck and the number of miles traveled by the semi truck which function can be used to find y the number of gallons of fuel remains in the rank of the semi truck after it was traveled x miles A. Y=240x-10
B y= 1/10x + 240
C y= 240x - 30
D y= -1/6x + 240
Any help pls?

Li buys supplies so he can make and sell key chains. he begins to make a profit only after he sells 4 key chains. what point on the graph makes the most sense in this situation?

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.

Which of the functions graphed below has a removable discontinuity?
