Answer:
At (-2,0) gradient is -4 ; At (2,0) gradient is 4
Step-by-step explanation:
For this problem, we simply need to take the derivative of the function and evaluate when y = 0 (when crossing the x-axis).
y = x^2 - 4
y' = 2x
The function y = x^2 - 4 cross the x-axis when:
y = x^2 - 4
0 = x^2 - 4
4 = x^2
2 +/- = x
Hence, this curve crosses the x-axis twice, once at (-2,0) and again at (2,0).
The gradient at these points are as follows:
y' = 2(-2) = -4
y' = 2(2) = 4
Cheers.
Answer:
125
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first term
1000/2000 = 1/2
We multiply each term by 1/2
2000, 1000, 500
To find the next term 500*1/2 = 500/2 = 250
To find the 5th term
250*1/2 = 125
Step-by-step explanation:
