Answer:
Step-by-step explanation:
We know the definition of both functions: 
, and 
A) In order to evaluate what 
, let's first investigate what g(-1) is using the definition for this function:
Now let's find what f(2) is using f(x) definition: 
B) In order to evaluate what 
, let's first investigate what f(3) is using the definition for this function:
Now let's find what g(7) is using the definition for this function:
Answer:
A = 1/2(y2-y1) (x3-x1)
A = 21 units^2
Step-by-step explanation:
The area of a triangle is 1/2 bh
Using the left side as the base b= 6 units
This is found by taking (y2-y1)
The height is 7 units, counting from the left side to x3
This is found by taking (x3-x1)
A = 1/2(y2-y1) (x3-x1)
A = 1/2 (6*7)
A = 1/2 *42
A = 21 units^2
