Question 10: Question 13: Question 11:

Step-by-step explanation:

For Question 10:

The functionis in the form of . We know the slope is (rise 1 run 2)and the y intercept is -1 (where the line goes through the y axis). We can then put the function is slope intercept form () and we would have .

For Question 13:

To evaluate the function for we need to plug -2 into the function as x. . times -2 would equal 3 because the negatives cancle out. 3-4 equals -1 so the solution is .

For question 11:

Same as question 13. plug 8 into x in . This would be . 8 squared is 64 and 64-4 is 60. Therefore .
