f(x)=4.75x, gives its domain and range
both domain and range are (-∞,+∞)
the domain for all polynomials is the same.
To find the domain and range of the function f(x) = 4.75x, we need to understand the concepts of domain and range.
The domain refers to all possible input values (x-values) for the function. In this case, since there are no restrictions or limitations on the input, the domain of f(x) is the set of all real numbers (-∞, ∞).
The range, on the other hand, refers to all possible output values (y-values) for the function. In this case, the function f(x) = 4.75x is a linear function with a constant slope of 4.75. This means that the output values depend on the input values scaled by a factor of 4.75. As x varies from negative infinity to positive infinity, the output values (y-values) will also vary from negative infinity to positive infinity. Therefore, the range of f(x) is also the set of all real numbers (-∞, ∞).
In summary:
Domain: All real numbers (-∞, ∞)
Range: All real numbers (-∞, ∞)
