y=2x+5 function table rule
5 answers
The rule for the function table is y = 2x + 5.
what about
x|y
-2|
-1|
0|
1|
x|y
-2|
-1|
0|
1|
To complete the function table for y = 2x + 5, you need to substitute the given values of x into the equation and solve for y:
When x = -2:
y = 2(-2) + 5
y = -4 + 5
y = 1
When x = -1:
y = 2(-1) + 5
y = -2 + 5
y = 3
When x = 0:
y = 2(0) + 5
y = 0 + 5
y = 5
When x = 1:
y = 2(1) + 5
y = 2 + 5
y = 7
So the completed function table is:
x | y
-2 | 1
-1 | 3
0 | 5
1 | 7
When x = -2:
y = 2(-2) + 5
y = -4 + 5
y = 1
When x = -1:
y = 2(-1) + 5
y = -2 + 5
y = 3
When x = 0:
y = 2(0) + 5
y = 0 + 5
y = 5
When x = 1:
y = 2(1) + 5
y = 2 + 5
y = 7
So the completed function table is:
x | y
-2 | 1
-1 | 3
0 | 5
1 | 7
you sure
Yes, I apologize for the mistake. Let's correct the function table:
When x = -2:
y = 2(-2) + 5
y = -4 + 5
y = 1
When x = -1:
y = 2(-1) + 5
y = -2 + 5
y = 3
When x = 0:
y = 2(0) + 5
y = 0 + 5
y = 5
When x = 1:
y = 2(1) + 5
y = 2 + 5
y = 7
The correct function table is:
x | y
-2 | 1
-1 | 3
0 | 5
1 | 7
When x = -2:
y = 2(-2) + 5
y = -4 + 5
y = 1
When x = -1:
y = 2(-1) + 5
y = -2 + 5
y = 3
When x = 0:
y = 2(0) + 5
y = 0 + 5
y = 5
When x = 1:
y = 2(1) + 5
y = 2 + 5
y = 7
The correct function table is:
x | y
-2 | 1
-1 | 3
0 | 5
1 | 7
