Question

A set of weights includes a 20lb barbell 6 pairs of plates are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f(x)=30x+20
Does this graph represent discrete or continuous situation?

Answer 1

Given f(x)=-6(1-x), what is the value of f(-8)?

Answer 2

The graph represents a continuous situation.

Answer 3

To find the value of f(-8), we need to substitute -8 into the expression for f(x) and evaluate it.

f(x) = -6(1-x)

f(-8) = -6(1-(-8))

f(-8) = -6(1+8)

f(-8) = -6(9)

f(-8) = -54

Therefore, f(-8) = -54.
