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".

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

11

step-by-step explanation:

32.50-7.50=25

225/25=11
