Answer:
y = x² - 5
Step-by-step explanation:
We need to find a function such that when we replace each value of x, we get the respective value of y.
So, the function that describes the relationship is:
y = x² - 5
Because, when we replace x by 2, we get:
y = 2² - 5 = 4 - 5 = -1
If x = 3
y = 3² - 5 = 9 - 5 = 4
If x = 4
y = 4² - 5 = 16 - 5 = 11
If x = 5
y = 5² - 5 = 25 - 5 = 20
