Answer:
y=4/7, x=-1/2
Step-by-step explanation:
Elimination is when you add the equations together
A function y = 3x² - 2 which is nonlinear function. the correct option is D.
In mathematics, linear refer to a proportional behaviour that can be modelled with a line, the functions that model this behaviour are called linear functions, and their graphs are lines.
Thus linear expression refers to an expression which has variables with an exponent equal to 1,
we know that Linear functions are in the form of y = mx + c and have a constant slope.
Noted that, the linear functions are polynomials with highest exponent equal to 1 and all others are non linear.
Here, answer is D) y = 3x² - 2, because the x is squared, making the function a quadratic function.
