In the first quadrant, the intersection point of the first-order function y = x + m and the inverse scale function y = m + 1 / X is p (Z, 3); Analytic expressions of linear function and inverse proportion function

In the first quadrant, the intersection point of the first-order function y = x + m and the inverse scale function y = m + 1 / X is p (Z, 3); Analytic expressions of linear function and inverse proportion function

(1) In the first quadrant, the intersection point of y = x + m and y = (M + 1) / X (M is not equal to 0) is p (Z, 3)
So we take y = m + 1 / X and y = x + M
3z=m+1
z+m=3
The solution is m = 2, z = 1
That is Z = 1
2、
Bring P (1,3) into
The analytic formula of a function is y = x + 2
The analytic expression of inverse proportion function is y = 3 / X

Why is it that if the images of sin (AX + b) and COS (Cx + D) are exactly the same
So a = C.

In the title, a and C both denote the frequency ω, t = 2 π / ω. If the symmetry axes of the two functions are exactly the same, then the period T is obviously the same, so the ω value of the two functions is the same, that is, a = C

Finding the symmetry axis of function image
The equation of symmetry axis of image with function y = sin (2x + 5 Π / 2)?

K Π + Π / 2 is the formula for finding the axis of symmetry of sin image. Later, we only need to make the formula after sin equal to it
2x + 5∏/2=k∏+∏/2
x =k∏/2-∏
This is the axis of symmetry of the graph of this function
Just do a few more questions
