Answer:
The answer to your question is : f(-2) = 2
Step-by-step explanation:
Just look for -2 in the x- axis and look for some line or point, vertical to number two.
In your example you can find a point two units upward the x-axis.
P ( x ) = x³ - 4 x² + 3 x - 12 =
= x² ( x - 4 ) +3 ( x - 4 ) = ( x - 4 ) · ( x² + 3 )
x - 4 = 0, x = 4
x² + 3 = 0, x² = - 3 ( there is no real solution )

Step-by-step explanation:
Explanation:
Suppose you know that:
Then note that:
So
We know that the error is approximately:
So we can confidently give the approximation:
Answer: 60
Step-by-step explanation:
Given : The number of choices for different temperatures = 3
The number of choices for different pressures = 4
The number of choices for different catalyst = 5
Since , the experimenter is studying the effects of temperature, pressure, and different type of catalysts.
Then by using the Fundamental principle of counting , we have
The number of experimental runs are available = (number of choices for temperatures ) x (number of choices for pressures) x( number of choices for catalyst)
= 3 x 4 x 5 = 60
Hence, the number of experimental runs are available = 60
