Answer:
x≥0 is correct inequality.
D is correct.
Step-by-step explanation:
We are given a function
We need to find x where function is defined.
As we know negative inside the root not defined.
Inside the root value must be greater than equal to 0.
Here we have inside the root is x.
Therefore, x must be greater than equal to 0.
Inequality: x≥0
Please see attached graph for more clarification.
Hence, x≥0 is correct inequality.
The function that is a tangent to the graph of f is
The definite integral can be interpreted as the resulting area of a region. In addition, it is a value in its result, that is, it does not depend on the variable x, which can be exchanged for any other variable without changing the value of the integral.
Knowing that :
- 40x + y = 0 is tangent of f(x)
- slope of the line = -40
therefore, f'(x)|x=a = -40, so only look for a we have:
if, x = -2, then y = 80 (since, 40x + y = 0), therefore, f(x) passes through (-2,80), so in the equation:
Therefore,
