Help me please ❤️❤️❤️❤️

Answer 1

In a quadratic function, $f(x)= ax^2+bx+c$ the leading coefficient is $a$, i.e. the coefficient of $x^2$, and the constant term is $c$, i.e. the coefficient without any power of $x$.

So, if you want leading coefficient 2 and constant term -3, your function needs to be like

$f(x)=2x^2+bx-3$

for any value of $b$. Among your options:

• The first is not a quadratic (it starts with $x^3$)
• The second has leading term -3 and constant term 2
• The third is not a quadratic (same as the first)
• The last is correct.
