Move a2 to the left side of the equation so you have c2-a2. then divide by 2 to get b by itself. you are left with c2-a2 all over 2. the 2s will cancel and you'll be left with c-a=b
Answer:
f(x) = -1/x
Step-by-step explanation:
Here, we want to find the function that is not linear
A linear function is of the form;
y = mx + b
where m can be zero, or b can be zero
The only option that does not follow this description is
f(x) = -1/x
