What is the leading coefficient in the polynomial y=3x^2-7 -7 x^2 2 3 3x^2

## Step 1: Identify the Leading Term<br />### The leading term of a polynomial is the term with the highest degree. In the polynomial $y = 3x^2 - 7$, the term with the highest degree is $3x^2$.<br /><br />## Step 2: Identify the Leading Coefficient<br />### The leading coefficient is the coefficient of the leading term. In the term $3x^2$, the coefficient is 3.
