Please write this equation as <span>f(x) = −18 + x^2 − 3x
Rewrite it in descending order by powers of x: f(x) = x^2 - 3x - 18
Since the coefficient of the x^2 term is +, the graph opens UP.</span>
1+3+3+4+6+9+9 is 35
7 numbers so divide by 7
35/7 = 5
Mean is 5
A parallel line must have the same slope. The only one it can be is A
