Answer 1

Hey mate

Hope this helps you...⬇️⬇️⬇️

$g(x) = 7x - 3 = 0 \\ 7x = 3 \\ x = \frac{3}{7} \\ \\ f(x) = {x}^{2} - x + 1 \\ { (\frac{3}{7}) }^{2} - ( \frac{3}{7} ) + 1 \\ \frac{9}{49} - \frac{3}{7} + 1 \\ \frac{9 - 21 + 49}{49} \\ \frac{19}{49}$

To find:

$(f - g)8 \\ = ( \frac{19}{49} - 0)8 \\ = \frac{152}{49}$
