Answer:
f(2)=-15
Step-by-step explanation:
y+4x^2-1 is the same as y=-4x^2+1, then replace y with f(x); f(x)=-4x^2+1. After you do that, replace x with 2; f(2)=-4(2)^2+1. 2^2=4, 4 times -4=-16, -16+1=-15. So f(2)=-15.
We can use the slope formula to find the slope between these two points:
2 - 6 / -1 - 4
-4 / -5
Because there are two negatives, they cancel out.
The slope of the line between these two points is 4/5.
