Viewed 218 times. 0. The function below is defined for continuous domains. Sketch the graph and state the range of the function. Question: f ( x) = 3 x + 2 for the domain { x ∈ R: x > 0 } The straight line cuts the y -axis at ( 2, 0) but since x > 0 why is the answer for the range still f ( x) > 2?

WebJan 4, 2024 · The range is y ∈ R − { 1 } Explanation: Factorise the numerator and denominator y = x 2 − 5 x − 6 x 2 − 3 x − 18 = ( x + 1 ) x − 6 ( x + 3 ) x − 6 = x + 1 x + 3 The denominator is ≠ 0 , therefore x + 3 ≠ 0 , ⇒ , x ≠ − 3 The domain of the function is x in RR- {-3} To determine the range, proceed as follows y = x + 1 x + 3 y ( x + 3 ) = x + 1 y x − … WebSolution: Function f: R → R is defined by f (x) = ex. Let x1, x2 ∈ R and f (x1) = f (x2) or ex1 = ex2 or x1 = x2. Therefore, f is one-one. Let f (x) = ex = y. Taking log on both sides, we get x = logy. We know that negative real numbers have no pre-image or the function is not onto and zero is not the image of any real number.
WebFinal answer. Transcribed image text: Given that F = 5x3,−9x3z2,−15x2z +y is a curl field, you must find a vector potential G such that ∇× G = F To do this, suppose that G = P,Q,R . Then P,Q,R must satisfy the three equations: 1. = ∂y∂R − ∂z∂Q 2. = ∂z∂P − ∂x∂R 3. = ∂x∂Q − ∂y∂P. Previous question Next question.

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 ...
