Question

A function has the function rule y = -7 x - 2. If the input is -4, what is the output? 26 -30 -26 14

Answer 1

Answer:

26

Step-by-step explanation:

Since the input is -4, x = -4. The equation then is y = -7(-4) -2

A negative times a negative is a positive, so -7 times -4 is 28.

Now the equation reads y = 28 - 2

Then obviously you just subtract the two and then you get 26.

Answer 2

Answer:

Answer:
