Answer:

Step-by-step explanation:
'x = -3', when graphed, passes through the point (-3,7) and (-3,0).
Since the line passes (-3,0), the x-intercept is -3.
(-3, 7) lies on the equation.
I have attached a picture of the graphed equation.
'x = -3' should be the correct answer.
Step-by-step explanation:
dy/dx
= d/dx [x / (1 - x²)]
= [(1 - x²)(1) - (x)(-2x)] / (1 - x²)²
= (1 + x²) / (1 - x²)².
When dy/dx = 1, (1 + x²) / (1 - x²)² = 1.
=> 1 + x² = 1 - x²
=> 2x² = 0, x = 0.
Also when x = 0, y = (0) / [1 - (0)²] = 0.
Hence the coodinates is (0, 0).
Answer:
m = 0.65
Step-by-step explanation:
40m-2=24
+2 +2
40m=26
÷ 40 ÷40
m=0.65
The y-intercept exists where x is 0. In our table, the y value is -4 when x is 0. So that's the place where the graph will go through the y axis. (0, -4) with -4 being the y-intercept.
