Implement the following functions in a Scala worksheet:

A polynomial can be represented as a list of monomials. A monomial is a pair of the form (coefficient, exponent). For example,

3x^2 5 is: List((3.0, 2.0), (-5.0, 0.0)) Implement:

evalMono(mono: (Double, Double), x: Double): Double = result of substituting x in mono

evalPoly(poly: List[(Double, Double)], x: Double): Double = resut of substituting x in poly
