A company is selling bubble gum. The function g(x)=3x+4 tells the company how much to charge if someone buys x packages of bubble gum. Find g(8) and tell what it means within the context of the problem.

g(8)=28. This means that 8 packages of gum costs $28.

g(8)=8. This means that after 8 packages of gum, the company makes $8.

g(8)=42. This means that 8 packages of gum costs $42.

g(8)=24. This means that 8 packages of gum costs $24.

What do you do to the b value to correctly complete the square?

divide it by 2 and square the result

divide it by 2 and take the square root of the result

When do you use the plus or minus symbol? ±

After taking the square root of both sides

After adding the square to both sides

After setting the equation equal to zero

A rational + Irrational is

irrational unless they are opposites

irrational unless the rational number is 0

For the function {(0,1), (1,-3), (2,-4), (-4,1)}, write the domain and range.

D: {1, -3, -4,} R: {0, 1, 2, -4}

D:{0, 1, 2, 3, 4} R:{1, -3, -4}
