Step-by-step explanation:
Problem 1:
Just plug in x=11
p(11)=5(11^2+1)+16=5(121+1)+16=5(122)+16=610+16=626
So p(11)=626 making D the correct answer
Problem 2:
Take note that because the slope is negative, the line will go down left to right. This means only C and D can be right. Because the slope is -4, this means we must choose the steeper line, therefore C is the correct answer
Problem 3:
Keep in mind that x^2+5x-6 can be factored into (x+6)(x-1). Using the Zero Product Property, the zeroes would be x=-6 and x=1. This means A is the correct answer
