Question

The function f is defined by f(x)= |x-2| -3, if f(a) = f(0) and a is greater than 0 what’s the value of a?

Answer 1

Answer: a =4

Step-by-step explanation:

Answer 2

Step-by-step explanation:

f(x)= |x-2| -3

f(a)= (a-2)-3 or (2-a)-3

f(0)= 2-3 = -1 = f(a)

So, (a-2)-3 = -1 or (2-a)-3 = -1

a= 4 or a = 0
