Question

determine whether the equation defines y as a function of x. y = x^2 + 5x + 3 does the equation define y as a function of x? yes no

Explanation:

Step1: Recall function definition

For a relation to be a function, for each input $x$ there must be exactly one output $y$.

Step2: Analyze given equation

For the equation $y = x^{2}+5x + 3$, if we substitute any real - number value for $x$, we will get a single, well - defined real - number value for $y$ through the operations of squaring, multiplication and addition.

Answer:

A. Yes
