Find the function h(x) = f(x).g(x) if f(x) = x(2 - x) and g(x) = 3x.
Solution:
Given, the function are
f(x) = x(2 - x)
On rewriting, f(x) = 2x - x2
g(x) = 3x
We have to find h(x) = f(x).g(x)
h(x) = (2x - x2)(3x)
= 6x2 - 3x3
Therefore, the value of h(x) is 6x2 - 3x3.
Example: Find the function h(x) = f(x).g(x) if f(x) = (3 - x) and g(x) = x.
Solution:
Given, the function are
f(x) = (3 - x)
g(x) = x
We have to find h(x) = f(x).g(x)
h(x) = (3 - x)(x)
= 3x - x2
Therefore, the value of h(x) is 3x - x2.
Find the function h(x) = f(x).g(x) if f(x) = x(2 - x) and g(x) = 3x.
Summary:
If f(x) = x(2 - x) and g(x) = 3x. The value of the function h(x) = f(x).g(x) is 6x2 - 3x3.
