The value pi/12 is the solution for the equation 2 cos^2 (4x) - 1 = 0 : true or false

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
