To find the values for output (y) for different input (x) using the given function rule, we substitute the values of x into the function rule and solve for y.
Given that the function rule is 2 less than 4 times x, we can write it as:
y = 4x - 2
Now, let's substitute the given values of x into the function rule to find the corresponding values of y:
For x = -1:
y = 4(-1) - 2
y = -4 - 2
y = -6
For x = 0:
y = 4(0) - 2
y = 0 - 2
y = -2
For x = 1:
y = 4(1) - 2
y = 4 - 2
y = 2
For x = 2:
y = 4(2) - 2
y = 8 - 2
y = 6
Hence, the completed table would look like this:
input(x) output(y)
-1 -6
0 -2
1 2
2 6
input(x): a number
output(y): 2 less than 4 times x
use the function rule to complete the table
input(x) output(y)
-1 ?
0 ?
1 ?
2 ?
