Given g(x) = x^2 - x, find g(2/3).
I got g(2/3) = -2/9. Is that right?
g(2/3) = (2/3)^2 - 2/3
= 4/9 - 2/3
= 4/9 - 6/9
= -2/9
Yeahhhh!
yay, thanks so much for checking :)
To find g(2/3), you need to substitute 2/3 into the function g(x) and simplify:
g(2/3) = (2/3)^2 - (2/3)
First, square 2/3:
(2/3)^2 = (2/3) * (2/3) = 4/9
Next, subtract 2/3:
4/9 - 2/3
To subtract these fractions, you need a common denominator, which is 9:
4/9 - 2/3 = 4/9 - (2/3) * (3/3) = 4/9 - 6/9 = -2/9
So, your calculation is correct. g(2/3) = -2/9.
