QF Q6.) Find the function for a.

irakobra [83]

The function for a is (f o g) (x) = 8x^2-10.

Explanation

=========================
$f(x)=2x-4, g(x)=4x^2-3, (f o g)=f(g(x))$

I already knew that the g of x is equal to $4x^2-3$ so I substitute inside of the g of x

$g(x)=4x^2-3$ =======> $f(x)=4x^2-3$ =============> $2(4x^2-3)-4$

simplify it

$2(4x^2-3)-4$ =======> $8x^2-6-4$ =========> $8x^2-10$

$(f o g) = 8x^2-10$

<u>Given</u>

Q(s) = -4s^3 + 7s^2 - 24;
s = -4 and 1

<u>Verifying zeroes</u>

Q(-4) =
