At first glance, a function looks just like a relation. Like a relation, a function has a domain and range made up of the x and y values of ordered pairs. A test known as vertical line test is used to know if the relation is a function, since the given data has different y values then it can already form a relation function without omitting a single point
the answer wuld be c (4,-2)
To solve for n in the equation d + 3n = 1, isolate n by subtracting d from both sides and then divide by 3.
To solve for n in the equation d + 3n = 1, we need to isolate the variable n. Start by subtracting d from both sides of the equation:
d + 3n - d = 1 - d
Simplify:
3n = 1 - d
Next, divide both sides of the equation by 3 to get the value of n:
n = (1 - d)/3
So, the solution for n is (1 - d)/3.
