The graph represents a linear function, because the graph is a line.
Linear basically means straight line. If you look at the line, it always goes left once and up once and this is always the same. This means the graph follows the equation of y = mx + c and so is linear. In this case, the equation is y = -x + 1
Which one do you want me to answer?
The degree of a line is 180, so..
Put it into an equation form: 5x + 75 = 180
1st combine like terms by subtracting 75 from 180
now your equation looks like this: 5x = 105
next you divide 5 from both sides, 105 divided by 5 is 21, so your answer is: x=21
I hope this helps!♥
Answer:
Step-by-step explanation:
f(x) = x²+3
f(a+1) = (a+1)²+3 = a²+2a+4
