$f(x) = 7x² + 99 × 23 - 67$

$f(9) = 7(9²) + 99 × 23 - 67$

$f (9) = 7(81) + 99 × 23 - 67$

$f(9) = 567 + 99 × 23 - 67$

$f(9) = 567 + 2.277 - 67$

$f(9) = 2.844 - 67$

$f(9) = 2.777$

f(x) = 7x² + 99 × 23 - 67

f(9) = 7(9)² + 99 × 23 - 67

f(9) = 7( 9 × 9 ) + 99 × 23 - 67

f(9) = 7(81) + 99 × 23 - 67

f(9) = ( 7 × 81 ) + 99 × 23 - 67

f(9) = 567 + 99 × 23 - 67

f(9) = 567 + 2.277 - 67

f(9) = 2.844 - 67

f(9) = 2.777
