The graph of the function f(x)= (x+2)(x-4) is shown. Which describes all of the values for which the graph is negative and increasing?
1) all real values of x where x < -2
2) all real values of x where -2< x <4
3) all real values of x where 1 < x < 4
4) all real values of x where x < 0​

answer

good luck on ur quiz test or homework. have a good day : )

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
