Answer:
False
Step-by-step explanation:
X = 5 goes to two different values of y so it is not a one to one correspondence. This is a relation not a function.
Answer:
Point slope form:
The equation of line is given by:
.....[1]
where m is the slope and a line contains a point
.
As per the given statement:
Slope(m) = 3
. = (2, 1)
Substitute these in [1] we have;

therefore, the point slope form of a line with slope 3 that contains the point (2, 1) is; 
Answer:
The expression will be 
Step-by-step explanation:
We have given expression 
We know the property of exponent that when two function are divided then the power of exponent is subtracted and when there is multiplication of two function then exponent is added
So
So the expression will be
