To find the equation for g(x), we know that g(x) is parallel to f(x) and passes through the point (1, 5). Since f(x) has a slope of 12, g(x) must also have a slope of 12 in order to be parallel. Using the point-slope form of a linear equation, we can write:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is the given point. Plugging in m = 12 and (x1, y1) = (1, 5), we get:
y - 5 = 12(x - 1)
Expanding and simplifying, we get:
y - 5 = 12x - 12
y = 12x - 7
Therefore, the equation for g(x) is y = 12x - 7.
