why f(x)=5-0.25x? Just this question please:)

4 N To find the blue shaded area above, we would calculate: f(x) dx = area Where: a = aaa X This is not a decimal or integer value. b aaa X H f(ac) aaa X 5 OC syntax error. Check your variables 4 - you might be using an incorrect one. Area = aaa X syntax incomplete
