help with this math problem. – Need domain, scope and results graphically?
f (x) =- 2x +5 help please! Details of step by step would be appreciated.
This graph is linear. Since all numbers real exist on the chart, we can say that: The image of the function is (- ∞, ∞), or "all real numbers. The Domain Service is (- ∞, ∞), or "all real numbers. However, to achieve the points where the function passes through, all you have to do is to replace any number you want for the "x". Thus, when x = 0, f (x) = -2 (0) + 5 f (x) = 5 Thus, the graph passes through point (0.5) When x = 1, f (x) = -2 (1) + 5 f (x) = -2 + 5 f (x) = 3 the function passes through the point (1,3) Now, try replacing the numbers following: If x = (-1), f (x) =? if x = 2, f (x) =? if x = (-2), f (x) =? Hope I helped!
