Difficulty: EasyFunction Notation and Transformations

The function ff has the property that f(3)=11f(3) = 11. The function gg is defined by g(x)=f(x)4g(x) = f(x) - 4. What is the value of g(3)g(3)?

Answer: 7

Answer

7
The value of g(3)g(3) is found by substituting x=3x = 3 into the equation g(x)=f(x)4g(x) = f(x) - 4, which results in g(3)=f(3)4g(3) = f(3) - 4. Substituting the given value of f(3)=11f(3) = 11 yields g(3)=114g(3) = 11 - 4, which simplifies to 77.

Step-by-Step Solution

1
Substitute x=3x = 3 into the function definition of g(x)g(x).
g(3)=f(3)4g(3) = f(3) - 4
To evaluate the function gg at a specific input, we replace xx with 33 in the definition g(x)=f(x)4g(x) = f(x) - 4.
2
Substitute the given value of f(3)=11f(3) = 11 into the equation.
g(3)=114g(3) = 11 - 4
The problem states that the value of f(3)f(3) is equal to 1111.
3
Simplify the expression to find the final value.
g(3)=7g(3) = 7
Subtracting 44 from 1111 yields 77.
