. the range of f x 2 – 3x x ∈ r and x 0
WebUsing the "partitioning the range of f" philosophy, the integral of a non-negative function f : R → R should be the sum over t of the areas between a thin horizontal strip between y = t and y = t + dt. This area is just μ{ x : f(x) > t} dt. Let f ∗ (t) = μ{ x : f(x) > t}. The Lebesgue integral of f is then defined by WebYes - that is how it works, if you have f (x)=x² and are asked what is f (2), then you replace every instance of x in the function definition with 2 so given f (x) = x², that means f (2) = 2² …

WebApr 16, 2024 · Then use the formula −b 2a. −b 2a = 0 6 = 0. the x-value of the vertex is 0. substitute it back in to get the y-value. f (0) = 3(0)2 −5 = 0 − 5 = − 5. So the vertex is (0, -5). The range is either y ≥ − 5 or y ≤ − 5. Since a is positive, the parabola opens upwards. So the range has to be y is greater than or equal to something.
