Let f(x) = 4x - 5 and g(x) = 6x - 3. find f(x) - g(x)?
Solution:
The domain of f(x) - g(x) consists of the values of x that are in the domain of f and the domain of g.
It is given that
f(x) = 4x - 5
g(x) = 6x - 3
We know that (f - g)(x) = f(x) - g(x)
Substituting the values
(f - g)(x) = (4x - 5) - (6x - 3)
By further calculation
= 4x - 5 - 6x + 3
So we get
= -2x - 2
Taking -2 as common
= -2(x + 1)
Therefore, f(x) - g(x) is -2(x + 1).
Let f(x) = 4x - 5 and g(x) = 6x - 3. find f(x) - g(x)?
Summary:
If f(x) = 4x - 5 and g(x) = 6x - 3 then the value of f(x) - g(x) is -2(x + 1).
