Final answer:

To solve for f(6), substitute x with 6 in f(x) = -5x + 4, yielding -26. For g(-2), substitute x with -2 in g(x) = -2x³ - 5, which gives 11.

Step-by-step explanation:

To find the values of f(6) and g(-2), we need to plug these values into the given functions.

f(x) = -5x + 4.
To find f(6), replace x with 6: f(6) = -5(6) + 4 = -30 + 4 = -26.

For g(x) = -2x³ - 5,
find g(-2) by substituting x with -2: g(-2) = -2(-2)³ - 5 = -2(-8) - 5 = 16 - 5 = 11.
