For this case the first thing that we must observe is the value of f (x) of the function in the table, when the value of x is x = -1
We then have that for x = -1, the value of the function is equal to 0.
Therefore, the following relationship is fulfilled:

Answer:
the value of f (-1) is:

Answer:
2(y-7) = 3
Step-by-step explanation:
Twice means multiply by 2.
The difference of a number and 7 means subtract a number/variable and 7.
Is equal to 3 means = 3.
2(y-7) = 3
Hope that helps.
Answer:
Perpendicular(p)=21
base(b)=20
hypotenuse(h)=29
Step-by-step explanation:
Now by using the formula:
cos A=b/h
i.e 20 by 29
The correct answer is real numbers
