find f(1) given that f(x)={(3x^21), (1/4), (3x+2), (x is less than or equal to 4), (4<x and x<2), (3x+2), (2 is less than or equal to x)}
(it's supposed to be a matrix)

Best ResponseYou've already chosen the best response.1ok this is called a piecewise function, the function changes for different x values. match the given x value with correct domain, then use that function to input the xvalue f(1) > 1 is between 4 and 2, so you would use f(x) = 1/4

Best ResponseYou've already chosen the best response.1another example: f(3) > 3 is greater than 2, so use f(x) = 3x+2 plug in x=3 > 3(3)+2 = 11 f(3) = 11

Best ResponseYou've already chosen the best response.0@dumbcow where did you get 1/4 from the fact that it is between 4 and 2?

Best ResponseYou've already chosen the best response.1because its given in the "matrix" x< 4 , 3x^2 1 4<x<2, 1/4 < x>2 , 3x+2
