Hey there :)
g ( x ) = 2x² - 11x
For g ( - 1 ) , you need to substitute - 1 in place of x
g ( - 1 ) = 2 ( - 1 )² - 11 ( - 1 )
= 2 ( 1 ) + 11
= 2 + 11
= 13 → Your answer
6^2 + 20.1^2 =? 22.9^2
36 + 404 does NOT equal 524.41
These do NOT form a right triangle.
10.5^2 + 20.8^2 =? 23.3^2
110.25 + 432.64 = 542.89
Therefore, it is a right triangle.
