Answer:
No because there are multiple Y values for the same X value. 3 is -1 and 1 at the same time meaning it is not a function.
Step-by-step explanation:
Answer:
Step-by-step explanation:
We need to evaluate 
(5+6i)(5+6i) = (25 + 36i² + 60i) = (25 - 36 + 60i) = -11 + 60i
= 
Now we rationalize the denominator.
Now, multiplying both the numerator and denominator by (6-i)
=
Formula used:
(a+b)² = a² + b² + 2ab
i² = -1

Answer:
f(− 3) = 84
Step-by-step explanation:
Given the function, f(x) = 7(9 − x), to find the value of f(-3) substitute x = -3 into the function:
f(− 3) = 7(9 − (− 3))
f(− 3) = 7(9 + 3)
f(− 3) = 7(12)
f(− 3) = 84
Therefore, f(− 3) = 84.
