Use the graph of f to estimate the local maximum and local minimum. (2 points)
a quartic graph is shown. the graph intercepts the x axis at approximately -2.8, 0, and 2.8.
local maximum: ∞ local minima: (-2,-4) and (2, -4)
local maximum: (0,0); local minimum: (-2,-4)
no local maximum; local minimum: (2,-4)
local maximum: (0,0); local minima: (-2,-4) and (2, -4)

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2

The answer would be a

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
