Circle the equations that represent quadratic functions a. y=3x+1 b. y=x^2+3 c. y=x^3-3 d. x^2+3y=8

Elena L [17]

Answer:

$B. y=x^2+3 \\\\D.$ $x^2+3y=8$

Step-by-step explanation:

A quadratic function is a function in which the highest power of the unknown variable is 2.

Formally, a quadratic function is defined as a function of the form:

$f(x)=ax^2+bx+c, a\neq 0$

From the given options, only B and D has the highest power as 2. Therefore, the equations that represent quadratic functions are:

$B. y=x^2+3 \\\\D.$ $x^2+3y=8$
