Which comparison is correct for the values of f(x) and g(x) when x= -2

function a: f(x)=3 -x^2

At x = -2, the correct comparison for the values of both functions can be represented by :

f(x) = g(x) or f(-2) = g(-2)

Step-by-step explanation:

We are given with two functions in this question, f(x) and g(x).

f(x) is given as:

f(x) = 3 - x^2

The equation of function g(x) is not given as such but their value for certain values of x are given.

What we need to compare are the values of both functions at x = -2.

g(-2) = -1      (Can be seen in the question given in the image)

f(-2) = 3 - (-2)^2

f(-2) = 3 - 4 = -1 which is equal to g(-2)
