Step-by-Step Solution

To solve this problem, we will follow these steps:

  • Step 1: Identify each term in the given function y=2x2+3y = 2x^2 + 3.
  • Step 2: Compare the equation to the standard quadratic form y=ax2+bx+cy = ax^2 + bx + c.
  • Step 3: Determine the coefficients aa, bb, and cc.
  • Step 4: Match these coefficients to the correct multiple-choice option.

Step 1: The given function is y=2x2+3y = 2x^2 + 3. There is no xx term present.

Step 2: Compare this with the standard form y=ax2+bx+cy = ax^2 + bx + c:

  • The coefficient of x2x^2 is a=2a = 2.
  • The coefficient of xx is b=0b = 0 because there is no xx term.
  • The constant term is c=3c = 3.

Step 3: Therefore, the coefficients are a=2a = 2, b=0b = 0, and c=3c = 3.

Step 4: Review the multiple-choice options provided:

  • Choice 1: a=0a = 0, b=2b = 2, c=3c = 3
  • Choice 2: a=0a = 0, b=3b = 3, c=2c = 2
  • Choice 3: a=2a = 2, b=0b = 0, c=3c = 3
  • Choice 4: a=3a = 3, b=0b = 0, c=2c = 2

The correct choice is Choice 3: a=2a = 2, b=0b = 0, c=3c = 3.

Therefore, the solution to the problem is the values a=2a = 2, b=0b = 0, c=3c = 3 which correspond to choice 3.

Answer

a=2,b=0,c=3 a=2,b=0,c=3
