Answer:
Adam plans to choose a video game from a section of the store where everything is 75 % off .
He writes the expression
Where d is the original price is d dollars.
75% off on d is represented as 0.75d.
And 0.75d is subtracted from original price d to get the price after discount. Hence, the equation forms
For example:
Let the price of an item be = $100
So, price will be = dollars

Rena correctly writes another expression,
This means that 25% of d will be charged.
This is also correct.
Same example as above.
Let the price be = $100
Price will be = dollars

x∈ {4,∞} y>0, above x-axis
Step-by-step explanation:
f(x)=
=0
For x∈ {-∞,-3} y<0, below x-axis
x∈ {-3,-1} y>0, above x-axis
x∈ {-1,4} y<0, below x-axis
x∈ {4,∞} y>0, above x-axis
