Question

Which is the polynomial function of lowest degree with leading coefficient of 4 and roots 7 and 3?
O f(x)= x2 – 3x-+3-17
O f(x)= 4x² -1245x+3/7
O f(x)=x2 – 3x? – X+21
O x) = 4x° – 12x – 28x+84

    Answer:

    Step-by-step explanation:

    If the roots are 7 and 3, then x = 7 and x = 3 are solutions. In factor form, x = 7 is (x – 7); in factor form, x = 3 is (x – 3). We FOIL these together to get

    x^2-3x-7x+21 which simplifies to

    x^2-10x+21 and we distribute in the 4:

    4(x^2-10x+21) to get

    4x^2-40x+84 which is another way to write the last choice you’re given.
