Final answer:
To evaluate the function f(x) when x=-10, the correct case of the piecewise function is used: f(-10) = 2(-10) - 4, which simplifies to -24.
Step-by-step explanation:
The student is asking for the value of a piecewise function f(x) when x=-10. The information provided regarding the definition of f(x) is incomplete; however, the only plausible choice for f(x) given that x equals -10 lies within the first case of the piecewise function. The first case of the piecewise function is represented as 2x - 4 for x less than or equal to -3.
To evaluate f(x) for x=-10, we substitute x with -10 into the first case of the function:
f(-10) = 2(-10) - 4
f(-10) = -20 - 4
f(-10) = -24
Therefore, the value of f(x) when x=-10 is -24.
