We first need to write the function in standard form.
y = -x^2 - 7x + 18
To find the axis of symmetry, we do -b/2a
The a and b are the coefficients of the x values.
So a would be -1 since -x is same as -1x
Follow that, b would be -7.
Then just plug the values in. - (-7)/2(-1) = -7/2
The axis of symmetry is -7/2
Answer:
the answer is insert menu
As you can see both drawings take up the same amount of surface area and the same amount of surface area is colored. The one on the right has 12 spaces, while the one on the left only has 3.
