Answer: ab -12
Given that y is 12 less than the product of a and b.
The product of a and b is the multiplication of a and b:
a x b = ab
12 less than the product will mean that we need to take away 12 from ab, so
y = ab - 12
-----------------------------------------------
Answer: ab - 12
-----------------------------------------------
Look at the x value, when it equals one.
We see that y = 0
Answer: y = 0
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
to get the slope of a straight line we only need two points off of it, hmmm let's use from the table (-1 , 13) and (2 , 1)

None of the above its actually number 22
Hope that helped!?

<span>Answer:
y = x + sin(x)
y' = 1 + cos(x)
Setting y' to zero, we have:
y' = 0
1 + cos(x) = 0
cos(x) = -1
x = pi, on the interval [0, 2pi]
y'' = -sin(x)
When x = pi, y'' = -sin(pi) = 0
Thus, we have an extremum at x = pi, but it is neither a local maxima nor a local minima.
Notice as well that y' = 1 + cos(x) >= 1 for all real values of x.
Thus, y is an increasing function.
This implies that on the interval [0, 2pi], the absolute minima is at x = 0, where y = 0 + sin(0) = 0; and the absolute maxima is at x = 2pi, where y = 2pi + sin(2pi) = 2pi.</span>
