Answer:
(X2+3)2
Step-by-step explanation:
First, you have to substitute in what f(x) equals for y since f(x) stands for y.
By doing this, the equation turns into (x2+3)2, because x2+3 is y, and 2 because the original equation way y2.
After you substitute, the answer is (x2+3)2.
Answer:
The unique intersection point for the given functions which is at x = 0.
The intersection point is (0,0)
Step-by-step explanation:
We are given the following information in the question.
We have to find the intersection point.
Equating the two equations we get,
Since the quadratic equation gives complex root, thus there is a unique intersection point for the given functions which is x = 0.
The attached image shows the graph for the given function.
The red line represent f(x) and blue line represent g(x).
The intersection point is (0,0)
P(-2.57 ≤ Z ≤ 1.27) = P(Z ≤ 1.27) - P(Z ≤ -2.57)
P(Z ≤ 1.27) = 0.8980
P(Z ≤ -2.57) = 1 - P(Z ≤ 2.57) = 1 - 0.99488 = 0.00512
P(-2.57 ≤ Z ≤ 1.27) = 0.8980 - 0.00512 = 0.89288
0.8929 (4 d.p.)
