What’s Question 6 and 7 ?

Step-by-step explanation:6.the factors need to be zero for the x-intercepts.but (-3 - 3) = -6 and not 0.the same for (-7 - 7) = -14 and not 0.his mistake was the signs. what do I need to add to -3 to get 0 ? 3. and 7 to -7.so, the correct f(x) isf(x) = (x + 3)(x + 7)to get x-intercepts at -3 and -7.7.in the same way we get the factors here : for a given x the y value has to be 0.how is y turning 0 for a polynomial in factor form ? well, at least one of the factors has to be 0.therefore, for (-6, 0) the factor has to be(x + 6) as -6 + 6 = 0for (2, 0) the factor has to be(x - 2) as 2 - 2 = 0pick one of them as your answer. they are both correct factors for f(x).
