Web3. Let x ∈ R satisfy x 7 + 5 x 2-3 = 0. Then x is not a rational number. Solution We use proof by contradiction. Suppose x 7 + 5 x 2-3 = 0 and x is rational, so we can write x = a b where a, b ∈ Z, b > 0 with gcd(a, b) = 1. Then a b 7 + 5 a b 2-3 = 0 a 7 + 5 a 2 b 5-3 b 7 = 0 Since a and b have no common factors, they cannot both be even ...

WebJul 18, 2024 · Find the domain and range of the following function: f(x) = 5x + 3 Solution Any real number, negative, positive or zero can be replaced with x in the given function. Therefore, the domain of the function f(x) = 5x + 3 is all real numbers, or as written in interval notation, is: D: ( − ∞, ∞). Web9 years ago. For every polynomial function (such as quadratic functions for example), the domain is all real numbers. If f (x) = a (x-h)² + k , then. if the parabola is opening upwards, i.e. a > 0 , the range is y ≥ k ; if the parabola is opening downwards, i.e. a < 0 , the range is y ≤ k .
WebThen the range of #f(x)# is the set of values of #f(x)# over #D#. We can think of this as the valid outputs. To determine the domain and range of a function, first determine the set of values for which the function is defined and then determine the set of values which result from these.
