Evaluate Algebraic Expressions with Given Parameters: a = -3, b = 3, c = 7

Choose the correct algebraic expression based on the parameters:

$a=-3,b=3,c=7$

To solve this problem, we will substitute the given values into the standard quadratic form:

• Step 1: Identify the formula to use. We need the standard form of a quadratic function, which is $y = ax^2 + bx + c$.
• Step 2: Substitute the given parameters into the formula:
  $a = -3$, $b = 3$, and $c = 7$.
• Step 3: Perform the substitution:
  Substituting in, we get $y = -3x^2 + 3x + 7$.

Therefore, the correct algebraic expression is $-3x^2 + 3x + 7$.

This corresponds to choice 2 of the multiple-choice options provided.
