To determine if the equation \(7x^2 + y = 5\) represents a linear or nonlinear function, we can analyze its form.
A linear function can be written in the form \(y = mx + b\), where \(m\) is the slope, and \(b\) is the y-intercept. Linear functions represent straight lines when graphed.
In the equation \(7x^2 + y = 5\), the term \(7x^2\) indicates that the function includes a quadratic term (specifically, \(x^2\)), which makes it a nonlinear function.
Therefore, the correct responses would be:
- The function \(7x^2 + y = 5\) is a nonlinear function.
- The function \(7 x^2 + y = 5\) is a nonlinear function.
- The graph of the function \(7x^2 + y = 5\) is not a straight line.
- The graph of the function \(7 x^2 + y = 5\) is not a straight line.
Hence, the statement about it being a nonlinear function is accurate.
