First, we calculate the z score

So, we have:




So:

From z score probability, we have:

Answer:
as x approaches infinity, y approaches negative infinity
as x approaches negative infinity, y approaches infinity
Step-by-step explanation:
let's look at the leading power of this graph. it is -4x^3, which means the leading power is 3. since this value is odd, it must go from either down to up or up to down. since the leading coefficient is negative, it goes from up to down (kind of like a negative slope).
Answer:
the slope is 3 and 1 and the y intercept is 1 and 1
Step-by-step explanation:
