The analytic formula of the line y 27x 101 about X axis symmetry is

The analytic formula of the line y 27x 101 about X axis symmetry is

The slope of the line y = 7x + 11 is k = - 7
The point of intersection with X axis is (- 11 / 7,0)
So the straight line is y-0 = - 7 (x + 11 / 7)
That is 7x + y + 11 = 0
If you don't understand, I wish you a happy study!

Let the image of the function y = - 3 (x-3) square be symmetric about the X axis, and the relation is

y=3(x-3)²

The maximum value of function y = Log & nbsp; 15 (x2-6x + 10) in interval [1,2] is ()
A. 0B. log 155C. log 152D. 1

The axis of symmetry of y = x2-6x + 10 is monotonically decreasing on x = 3, X ∈ [1,2]. From the monotonicity of the composite function, we can see that in the function y = Log & nbsp; 15 (x2-6x + 10), y = Log & nbsp; 15 (x2-6x + 10) is an increasing function on the interval [1,2], so the maximum value of [1,2] is log & nbsp; 15 (22-6 × 2 + 10) = Log & nbsp; 152
