Input (x) while output (y)
Plug it into the equation
1. y = 2/2 + 1. Output = 2
2. y = 4/2 + 1 Output = 3
3. y = 7/2 + 1 output = 4.5
4. y = 9/2 + 1 Output = 5.5
<span>f(x)=2x+1 and g(x)=x^2-7
(f+g)(x) = </span>2x + 1 + x^2 - 7
(f+g)(x) = x^2 + 2x - 6
answer
x^2 + 2x - 6
Answer:
The given function is
Notice that this function is linear, that means its graph is a straight line.
To graph a linear funtion you just need to use two coordinates.
For
For
So, the points you need are and .
The image attached shows the graph of the given function, where you can observe the two ponints we used.
Separate into two inequalities.
1x < 3
1x > -15
Solve for x.
x < 3
x > -15
