Answer:
Domain = {3,4,9}
Range = {2, 6, 8, 9.5}
Given relation is NOT a function.
Step-by-step explanation:
Given relation is relation is ((9,6), (3,8),(4,9.5), (9,2)}.
Now we need to determine if given relation is a function or not.
We also need to find the domain and range.
((9,6), (3,8),(4,9.5), (9,2)}
Domain is basically the collection of x-values
So Domain = {3,4,9}
Range is basically the collection of y-values
So Range = {2, 6, 8, 9.5}
Since given relation contains repeated x-value "9".
So the given relation is NOT a function.
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 2.5) and (x₂, y₂ ) = (2, 1) ← 2 points on the line
m = =
=
Note the line crosses the y- axis at (0, - 2.5) ⇒ c = - 2.5 = -
y = x -
→ A
