Answer:
2
Step-by-step explanation:
If the value of the discriminant is positive, there are two real solutions for x, meaning the graph of the solution has two distinct x-intercepts
Here 25 is positive discriminant, hence the function will have 2 x - intercepts
The probability of spinning a red is 2/5
<h3>Probability</h3>
Probability is the likelihood or chance that an event will occur
- Probability = Expected/Total outcome
Given the following information
- Total number of spin = 30 spin
- Number of times it lands on red = 12 times
Pr(spinning a red) = 12/30
Pr(spinning a red) = 2/5
Hence the probability of spinning a red is 2/5

we have that

using a graph tool
see the attached figure
statements
case a) The domain is {x|x ≤ –2}-------> Is False
the domain is all real numbers---------> the interval (-∞,∞)
case b) The range is {y|y ≤ 6}.------> Is True
The range is the interval (-∞,6]
case c) The function is increasing over the interval (–∞ , –2).-----> Is True
See the attached figure
case d)The function is decreasing over the interval (−4, ∞).-----> Is False
In the interval (-4,-2) the function is increasing and in the interval (-2,∞) the function is decreasing (See the attached figure)
case e)The function has a positive y-intercept.------> Is True
The value of y-intercept is 
Step-by-step explanation:
it is option c. you interchange the value with y and take inverse.
