Someone help asap! pls

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

The transitive property of equality states that: o if a = b, then bra o if a = b, then ac = bc o if a = b and b= c, then a = if a = b and c= c, then a + b = b + c

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).
