Which of the following best describes this equation? y = 4x2 + 7
A. neither linear nor non - linear
B. both linear and non-linear
C. linear
D. non-linear

C. Linear

Step-by-step explanation:

both the slope and y-intercept is positive and if you make the graph their linear

Option C is correct.

Step-by-step explanation:

The given equation or function is linear if the variables x and y have degree zero or 1.

The given equation is 5x^4+5y =9

here x has degree =4 and y has degree = 1, but for linear equation both x and y variables must have degree zero or 1.

So, Option C is correct.
