Notice how f(0) is 0 on the graph, it can only be 3 because 3 is the only number on the y-axis that the line runs through. The line does not run through any of the other options.

Which quadratic equation fits the data in the table? (PICTURE OF TABLE ATTACHED)

Paha777 [63]

The correct quadratic equation for that set of points is:
$y=x^2+7x+1$

To check it, simply put first and last pair of points and assure the equality:
$-11=(-3)^2+7*(-3)+1$
$-11=9-21+1$
$-11=-11$

$79=6^2+7*6+1$
$79=36+42+1$
$79=79$
