A dog groomer charges her clients by the weight of the dog. The following piecewise function represents the total charge, f(x)
, for a dog weighing x pounds.
f(x)=⎧⎩⎨⎪⎪2.5x if 0≤x≤203.5x if 20 <x≤50 5x if x>50
What would be the last point graphed on the first piece of the function, f(x)=2.5x
?
The last point graphed on the first piece of the function, f(x) = 2.5x, would be when x = 20.
To find the value of f(x) when x = 20, we substitute x = 20 into the equation:
f(20) = 2.5 * 20 = 50
Therefore, the last point graphed on the first piece of the function would be (20, 50).
