write a rule for each function table
8x - 15 is this correct??? HELP
To determine if the rule 8x - 15 correctly represents the function table, let's test it with the given input-output pairs:
For X = 1:
8(1) - 15 = 8 - 15 = -7
The expected output is 1, but the rule gives -7. Therefore, the rule of 8x - 15 is incorrect.
To find the correct rule, let's analyze the given input-output pairs:
Input X Output Y
1 1
3 9
5 25
By observing the pattern, we can see that the output Y is equal to the square of the input X. Hence, the correct rule for this function table is Y = X^2.
