<h3>Graph of a function</h3>From the question, we are to determine the value of f(0) and the roots of f(x) = 0
The value of f(0) is the value of f(x) or the value of y when x = 0
In the given graph, we can observe that the value of y when x = 0 is 2
∴ f(0) = 2
The roots of f(x) = 0 correspond to the values of x when f(x) = 0 or when y = 0
In the graph, we can observe that the values of x when f(x) = 0 are -2 and -1
∴ The roots of f(x) = 0 are -2 and -1
Hence, the value of f(0) is 1
and
The roots of f(x) = 0 are -2 and -1

Step-by-step explanation:
From the question we are told that
The sample size is n = 15
The difference in population proportion is
Generally the sample mean of the input temperature is
=>
=>
Generally the sample mean of the output temperature is
=>
=>
Generally the difference of the sample mean of the input temperature and that of the output temperature is
=>
=>
Generally the standard deviation is mathematically represented as
=>
=>
=>
=>
Generally the degree of freedom is mathematically represented as
=>
=>
Generally the probability of t obtained from the t - distribution table at a degree of freedom of is
Generally the p-value is mathematically represented as
=>
=>
From the values obtained we see that hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
The cooling system changes the temperature of the water by 6 degrees.
