Answer:
The slope of the function is ²/₃ and since the second derivative is zero, the concavity doesn't exist.
Step-by-step explanation:
Given;
x = 6t
y = 4t - 3
point t = 4

The slope of the function is ²/₃
take the second derivative of the function;
the second derivative will be zero since the first derivative is a constant value.

Since the second derivative is zero, the concavity doesn't exist.
A’ -9,0. B’ 0,12. C’ 9,0. D’ 0, -12. As long as u put the in order when u listed them that’s the way I put them.
First term, n=1: 2*1 -3 = -1
Second term, n=2: 2*2 -3 = 1
Third term, n=3: 2*3 -3 = 3
