F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

The trigonometric ratios sine and secant are reciprocals of each other

Consider the input and output values for f(x) = 2x - 3 and g(x) = 2x + 7. what is a reasonable explanation for different rules with different input values producing the same sequence?
