Calculate f(4) for each function below

Answers

The question is about Evaluating Functions and to calculate f(4) for each function, we substitute 4 into the function and simplify. The values of f(4) for the given functions are: a) 16, b) 12, c) 5.6569, d) 0, e) 8, f) 44y.

Evaluating functions involves determining the output (or value) of a mathematical function for a given input (or argument). It's done by substituting the input value into the function's equation and solving for the result. In the context of functions like f(x), you replace 'x' with the specific value you want to assess. This process helps analyze how a function behaves, finding its y-value or dependent variable. Evaluating functions is crucial in various fields, such as mathematics, science, and engineering, to understand relationships and make predictions based on input-output mappings.

To calculate f(4) for each function, we substitute 4 into the function and simplify. Let's calculate:

a) f(x) = x2
Substitute 4 into the function:
f(4) = 42 = 16

b) f(x) = √144
Substitute 4 into the function:
f(4) = √144 = 12

c) f(x) = √32
Substitute 4 into the function:
f(4) = √32 ≈ 5.6569

d) f(x) = 3x - 12
Substitute 4 into the function:
f(4) = 3(4) - 12 = 0

e) f(x) = (x - 2)^3
Substitute 4 into the function:
f(4) = (4 - 2)^3 = 8

f) f(x) = 4xy + 7xy
Substitute 4 into the function:
f(4) = 4(4)y + 7(4)y = 16y + 28y = 44y
