<h3><u>Answer:</u></h3>
Hence, the equation of line is:
y= -6x
<h3><u>Step-by-step explanation:</u></h3>Clearly from the graph we could see that the line passes through the point (0,0) and (-1/2,3).
Also we know that the equation of a line passing through (a,b) and (c,d) is given as:
Here we have:
(a,b)=(0,0) and (c,d)=(-1/2,3)
Hence, the equation of line is:
Hence, the equation of line is:
y= -6x
It looks like you might have intended to say the roots are 7 + i and 5 - i, judging by the extra space between 7 and i.
The simplest polynomial with these characteristics would be
but seeing as each of the options appears to be a quartic polynomial, I suspect f(x) is also supposed to have only real coefficients. In that case, we need to pair up any complex root with its conjugate to "complete" f(x). We end up with
which appears to most closely resemble the third option. Upon expanding, we see f(x) does indeed have real coefficients:
