Graph the piecewise function (20 points! ) (image provided below)

check the picture below.

notice, the hollow dot endpoints, is where the subfunction does not include that value of "x", and where the dot is a solid dot, that value is included in the subfunction.

so the piece-wise is simply the composition of all its subfunctions, in this case 3 subfunctions, within their range, notice the lines continue on the dashed line part, but that part is not included in the piece-wise because is outside the range provided for "x".

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
