To determine at what x-value the first function becomes greater than the second function, we can set the two functions equal to each other and solve for x.
First function: y = 3
Second function: y = x + 2
Setting the two functions equal to each other:
3 = x + 2
Subtracting 2 from both sides:
1 = x
Therefore, at x = 1, the first function becomes greater than the second function.
1.
ITEM 11
There are two functions below. At what x-value does the first function become greater than the second function.

x
y=x+2
Hint: Make a table to compare each function.
