For the function \( f(x) = 3x^2 - 2x + 5 \), find:

\( f(1) \), \( f(-2) \), and \( f(a) \).

f ( x ) = 3 x 2 − 2 x + 5 f ( 1 ) : S u b s t i t u d e 1 a s x in t o f u n c t i o n : f ( 1 ) = 3 ∗ 1 2 − 2 ∗ 1 + 5 = 3 − 2 + 5 = 6 f ( − 2 ) S u b s t i t u d e x = − 2 f ( − 2 ) = 3 ∗ ( − 2 ) 2 − 2 ∗ ( − 2 ) + 5 = 3 ∗ 4 + 4 + 5 = 12 + 4 + 5 = 21 f ( a ) s u b s t i t u d e x = a f ( a ) = 3 a 2 − 2 a + 5 ​

The function evaluations are: f ( 1 ) = 6 , f ( − 2 ) = 21 , and f ( a ) = 3 a 2 − 2 a + 5 .
