Ayúdenme es urgente 1. Escribe una expresión lineal con variable x, que valga 1 cuando x = 1 y valga 7 cuando x = 3. 2. Escribe una expresión lineal con variable x, que valga −1 cuando x = −1 y valga −5 cuando x = 0.

Quadrilateral wxyz is on a coordinate plane. segment yz is on the line x+y=7 and segment xw is on the line x+y=3. which statement proves how segments yz and xw are related

The step function g(x) is defined as shown.what is the range of g(x)? ***answer choices in picture.

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.
