The function y = 2x + 8 represents the cost y (in dollars) of a large pizza with x toppings, where x is equal to 0, 1, 2, or 3.
Identify the independent and dependent variables, the domain, and the range.

0 ,1,2,3,/ is range/ y is the independent varibal/ x is the dependent varible/ /the equation is the domain

Step-by-step explanation:

a negative exponent is translated as follows:

so, we have

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
