Answer:
Depends on the domain and the graph.
Step-by-step explanation:
Answer:
The length for the first one is 97 degrees
The last answer: 2 or 0
Explanation:
When you graph this function, it crosses the x-axis once. In other words, that means there is only 1 real zero and 2 imaginary complex zeros. In addition, imaginary solutions always come in pairs, so there can’t be a odd number of them such as 3.
Answer:
![f(2) = 81](https://tex.z-dn.net/?f=f%282%29%20%3D%2081)
![g(2) = 83](https://tex.z-dn.net/?f=g%282%29%20%3D%2083)
Science class had a higher average
Step-by-step explanation:
Given
![f(x) = 0.5x + 80](https://tex.z-dn.net/?f=f%28x%29%20%3D%200.5x%20%2B%2080)
g(x) table
Solving (a): f(2)
We have:
![f(x) = 0.5x + 80](https://tex.z-dn.net/?f=f%28x%29%20%3D%200.5x%20%2B%2080)
So:
![f(2) = 0.5*2 + 80](https://tex.z-dn.net/?f=f%282%29%20%3D%200.5%2A2%20%2B%2080)
![f(2) = 1 + 80](https://tex.z-dn.net/?f=f%282%29%20%3D%201%20%2B%2080)
![f(2) = 81](https://tex.z-dn.net/?f=f%282%29%20%3D%2081)
Solving (b): g(2)
From the given table.
![g(2) = 83](https://tex.z-dn.net/?f=g%282%29%20%3D%2083)
Solving (c): f(4) or g(4); which is greater
![f(x) = 0.5x + 80](https://tex.z-dn.net/?f=f%28x%29%20%3D%200.5x%20%2B%2080)
So:
![f(4) = 0.5*4+80](https://tex.z-dn.net/?f=f%284%29%20%3D%200.5%2A4%2B80)
![f(4) = 2+80](https://tex.z-dn.net/?f=f%284%29%20%3D%202%2B80)
![f(4) = 82](https://tex.z-dn.net/?f=f%284%29%20%3D%2082)
For g(4): Notice that in the table of g(x); g(x) increases by 2 when x increases by 1
This means that:
![g(x) = g(x-1)+2](https://tex.z-dn.net/?f=g%28x%29%20%3D%20g%28x-1%29%2B2)
So
![g(4) = g(4-1)+2:](https://tex.z-dn.net/?f=g%284%29%20%3D%20g%284-1%29%2B2%3A)
![g(4) = g(3)+2](https://tex.z-dn.net/?f=g%284%29%20%3D%20g%283%29%2B2)
![g(4) = 85+2](https://tex.z-dn.net/?f=g%284%29%20%3D%2085%2B2)
![g(4) = 87](https://tex.z-dn.net/?f=g%284%29%20%3D%2087)
<em>Hence, g(4) i.e. Science class is greater</em>
