Step-by-Step Solution

To create an algebraic expression based on the parameters provided, we need to follow these steps:

  • Step 1: Recognize the standard form of a quadratic function: y=ax2+bx+c y = ax^2 + bx + c .
  • Step 2: Identify and substitute the given values a=3 a = 3 , b=4 b = 4 , and c=15 c = -15 into this form.
  • Step 3: Substitute to form the expression: y=3x2+4x15 y = 3x^2 + 4x - 15 .

Step 1: We recognize that we are dealing with a quadratic equation in the form y=ax2+bx+c y = ax^2 + bx + c .

Step 2: Using the values given in the problem statement, substitute a=3 a = 3 , b=4 b = 4 , and c=15 c = -15 into this standard form equation:

y=ax2+bx+cy=3x2+4x15 y = ax^2 + bx + c \rightarrow y = 3x^2 + 4x - 15

Step 3: This substitution gives us the algebraic expression:

3x2+4x15 3x^2 + 4x - 15

Therefore, the expression based on the given parameters is 3x2+4x15\mathbf{3x^2 + 4x - 15}.

Answer

3x2+4x15 3x^2+4x-15
