Answer:

Step-by-step explanation:
The function is given :
f(x) = 4x + 15
For f(-3), the input for the function f(x) is -3.
Replace the x variable with -3.
f(-3) = 4(-3) + 15
Evaluate.
f(-3) = -12 + 15
f(-3) = 3
The output for f(-3) is 3.
He can change 1/6 and 1/3 to make their denominators 12, so it would be 2/12 and 4/12
A conjuate is real numbers like the conjuate of x and y would be a real number
