Step-by-step explanation:
g(x) = 3x² + 2x - 1
g(-1) = 3(-1)² + 2(-1) - 1
= 3(1) -2 -1
= 3 - 3
= 0
Answer:
X^2-18x+81
OR
(X-9)^2
Step-by-step explanation:
X(x-9)-9(x-9)=
x^2-9x-9x+81
X^2-18x+81
The formula is 1/2 times base times height. So,your answer is B
The distance would be 3 units because the difference between 2 and 5 is 3.
I think it would be the first one because the y intercept is 8 and to find the gradient u do rise/run
