we have y = x + 2
our equation is y = x + 2
y is dependent on x
we have x to be -2, -1 0, 1 and 2
for x = -2
y = -2 + 2
y = 0
for x = -1
y = -1 + 2
y = 1
for x = 0
y = 0 + 2
y = 2
for x = 1
y = 1 + 2
y = 3
for x = 2
y = 2 + 2
y = 4
From the values of x and y gotten, we can observe that y increases as x increases
Therefore the equation is a function
x -2 -1 0 1 2
y 0 1 2 3 4
