What is the correct function to model this situation?
y = {x + 3}
y = {x - 3}
y = 3{x}
y = {3x}

What are the coordinates of the point that is 1/3 of the way from a to b? a (2,-3) b (2,6)

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.

X+y=-4 x-y=2 use elimination with adding and subtraction
