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?
The graph represents a continuous situation.
Given f(x)=-6(1-x), what is the value of f(-8)?
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.
