Answer:
- the value of the function changes sign in the interval
- the function is monotonic in the interval
Step-by-step explanation:
All polynomial functions are continuous, so we know from the intermediate value theorem that if the expression on the left changes sign in the interval [-2, 1] then there will be a zero in that interval. If the function is monotonic in the interval, there can only be one zero.
a) For f(x) = x^3 +x +3 = (x^2 +1)x +3, the values at the ends of the interval are ...
f(-2) = (4+1)(-2) +3 = -7
f(-1) = (1 +1)(-1) +3 = 1
The function value goes from -7 to +1 in the interval, so there exists at least one root in that interval.

b) The derivative of the function is ...
f'(x) = 3x^2 +1
This is positive for any x, so is positive in the interval [-2, -1]. That is, the function is continuously increasing in that interval, so cannot have more than one crossing of the x-axis. There is exactly one root in the interval [-2, -1].
Answer:
The answer to this question is simply NO. There is exactly one line through any two points and exactly one plane through any three points not on the same line. Therefore, any two points on the prism must be collinear and coplanar.
...
Step-by-step explanation:
We have been asked that:
is it possible for two points collinear nor coplanar?
<u>Collinear points:</u>
Collinear points are points that lie on the same line.
<u>Coplanar points:</u>
Coplanar points are points that lie on the same plane.
The answer to this question is simply NO. There is exactly one line through any two points and exactly one plane through any three points not on the same line. Therefore, any two points on the prism must be collinear and coplanar.

If 9 of the sparrows is 45% of the birds in the backyard, 9/x = 45/100.
Cross multiply to get 9 * 100 = 45x; simplified is 900 = 45x or 20.
This means that there are 20 birds in the backyard. You can check this by dividing 9/20 which equals 45%
