Answer:
The expression with three terms to show the price of a gallon of gas on Saturday is ⇒
Step-by-step explanation:
Given:
Price of a gallon of gas in dollars =
On Friday, the price goes up by = $0.05
On Saturday, the price goes down by = $0.03
To write an expression with three terms to show the price of a gallon of gas on Saturday.
Solution:
Initial price of a gallon given in dollars was =
On Friday the price increased by $0.05.
So, the price on Friday in dollars can be given as =
On Saturday, the price decreased by $0.03
So, the price on Saturday in dollars can be given as =
Thus, the expression with three terms to show the price of a gallon of gas on Saturday is ⇒
Answer:
Horizontal translation in the direction.
Step-by-step explanation:
A function of the form experiments an horizontal translation when the following substitution is applied:
, where
If , the function is translated in the
direction, whereas
is the case for the function being translated in the
direction.
The effect on the graph can be defined by a composition between two function:
,
The resulting expression represents a horizontal translation in the direction.
Finally, we plot (red) and
(blue) by a graphing tool and proved the certainty of this theory.
