Question

If f(x) = 42 - 5 and g(x) = 3x+ 7, which of the following statements are true?

I f(0) = g(-4)
II f(-2) - 9(2)
III f(0) = g(3)
IV f(6) - g(4)

Α. I only
B. I and IV only
C. II and III only
D. All are true

Answer 1

Your final answer would be b 1 and 4

Answer 2

B. I and IV only

Explanation:

You replace the x with the numbers in the parenthesis. So for I it would be:

f(0) = 4(0) - 5 -> 0 - (-5) -> -5

g(-4) = 3(-4) +7 -> -12 + 7 -> -5

You solve each one and if your answer matches with each other, your answer is right.

If you did this with II and III, you wouldn't get the same answers.

For IV it would be:

f(6) = 4(6) - 5 -> 24 - 5 -> 19

g(4) = 3(4) + 7 -> 12 + 7 -> 19
