If both the functions f(x) and g(x) are equal. Then the value of the variable will be 3.
What do you understand by the term y = f(x) ?
The term f(x) is used to represent a function of x i.e. a function with only one independent variable ' x '.
The functions are given below.
f(x) = x³ - 3x² + 2 and g(x) = x² - 6x + 11
If both the functions f(x) and g(x) are equal.
f(x) = g(x)
x³ - 3x² + 2 = x² - 6x + 11
Simplify the equation, then we have
x³ - 4x² + 6x - 9 = 0
Then the equation is solved by the calculator, then we have
x = 3
Then the value of the variable will be 3.
