Let f and g be re

Answer :

Given: f and g be real functions defined by f(x) = 2x + 1 and g(x) = 4x-7


To find: For what real numbers x, f (x) = g (x)


Explanation: to satisfy the condition f(x) = g(x), the given real functions should be equal


i.e., 2x + 1 = 4x-7


7 + 1 = 4x-2x


8 = 2x


Or, 2x = 8


x = 4


Hence for x = 4, f (x) = g (x)
