The equation in slope intercept form for the line with slope 3 and Y intercept -1 is y = 3x -1 .
If x + 1 is a factor then f(-1) will = zero.
f(-1) = 8 so its not answer a).
f(3) = 0 so the answer is x - 3
Its c.
Can you Elaborate your question?
Actually, this answer would be true. Why?
The first equation is: a(sub <em>n</em>) = 8, 13, 18, 23
The second is: a(sub 1)=8 ; a(sub <em>n</em>)= a(sub <em>n</em>-1)+5
if you wish to find the second term, plug two into the equation for <em /><em>n</em>
8+5=13
to find the third, plug the second term, 13, in for <em>n.</em>
13+5=18.
Hope this helped! I know it's a bit on the late side, but at least you can get the general idea!
The answer for this question is 13/5 greatre than 1.9
