Someone can help me with 31 & 33? i need help
nika2105 [10]

31. It gives you the equation f(x) = -2x + 4 and asks you to solve for f(12). To solve this you must replace x in the equation -2x + 4 with 12 like so:

-2(12) + 4

Remember that when solving this use your rules of PEMDAS. In this case you will first multiply -2 and 12 then add the product with 4

-24 + 4

f(12) = -20

33. Replace x in the equation x³ - x with 5 like so...

5³ - 5

Again, remember to use the rules of PEMDAS to solve this. First take the cube of 5 then subtract 5 from the answer

125 - 5

g(5) = 120

Hope this helped!
