A student claims that the function f(x) = x^4 is strictly convex over its entire domain (all real numbers). Which of the following statements best evaluates this claim?

A function whose first derivative is a strictly increasing function over its entire domain must be a strictly convex function.

Distinguishing Between Convex and Strictly Convex Functions

Match each function to its correct convexity property over its entire domain of all real numbers.

A function g(x) has a first derivative g'(x) = e^x. For all real numbers x, the function g(x) must be a ____ function.

The slope of a function's tangent line is observed to be strictly increasing at every point across its entire domain. For example, as the input x increases, the slope might change from -2 to -1, then to 0, then to 1.5, and so on, never decreasing or staying constant. Based on this information alone, what can be concluded about the function?

A function is defined as strictly convex when its second derivative is strictly greater than zero. Given the function f(x) = x³ - 6x² + 5x + 10, determine the interval over which the function is strictly convex.

You are given a twice-differentiable function, f(x), and asked to determine if it is strictly convex. Arrange the following steps into the correct logical sequence to perform this analysis.
