1. f(x) = 3x + 1
2. g(x) = 2x^2 + 5
To determine which function has the greater rate of change, we can compare the slopes of the two functions. The slope of a linear function (such as f(x)) is constant and equal to the coefficient of x. In this case, the slope of f(x) is 3.
The rate of change of a quadratic function (such as g(x)) is not constant and varies depending on the value of x. To compare the rate of change of g(x) to f(x), we can look at the slopes of the two functions at a specific point or over a specific interval.
In general, a quadratic function has a greater rate of change than a linear function. Therefore, g(x) = 2x^2 + 5 has a greater rate of change than f(x) = 3x + 1.
3. f(x) = 4x^3 + 2x^2
4. g(x) = 5x^2 + 3x
To determine which function has the greater rate of change, we can compare the slopes of the two functions. The slope of a cubic function (such as f(x)) is not constant and varies depending on the value of x. The slope of f(x) can be calculated by taking the derivative of the function, which results in f'(x) = 12x^2 + 4x.
The slope of a quadratic function (such as g(x)) is not constant and varies depending on the value of x. The slope of g(x) can be calculated by taking the derivative of the function, which results in g'(x) = 10x + 3.
At any given point or over a specific interval, the rate of change of a cubic function can vary compared to that of a quadratic function. Therefore, it is not possible to definitively determine which function has a greater rate of change without more specific information.
