Functions are used to represent graphs, and vice versa.
The function represented by the graph is 
The graph (see attachment) is an absolute value graph.
An absolute value graph is represented as:

Where

The vertex is the minimum or the maximum point on the graph.
So, we have:

The function becomes

The function also passes through the point (-1,0).
So, we have:


Remove the absolute bracket

Subtract 3 from both sides

Divide both sides by 3

Substitute -1 for (a) in 

Hence, the function represented by the graph is

Answer:
152 - 4d
Step-by-step explanation:
You had $152
$4 is spent each day
Let d represent the days
Since the money at hand is $152 and $4 is taken away each day then, the algebraic expression which models this situation is
= 152-4d
Answer:
105°
Step-by-step explanation:
total angle of triangle equals 180°
so,
25° + 50° + ? = 180°
? = 180° - (25° + 50°)
? = 180° - 75°
? = 105°
So third angle of a triangle is 105°
You would have to do 11 plus 6 multiplied by 5 to find the amount of money needed to find the total cost of 5 T-shirts
There is a 35% chance the first one will not work, and a 49% the second one will not work. (Theoretically there is an 81% chance neither of them will work.)
