I need help it’s hard
Reika [66]

9514 1404 393

Answer:

  f^-1(x) = (x +4)/3

Step-by-step explanation:

The inverse function is found by swapping x and y, then solving for y.

  y = 3x -4 . . . . . function y = f(x)

  x = 3y -4 . . . . . inverse relation

  x +4 = 3y . . . . add 4

  (x +4)/3 = y . . . divide by 3. This is the inverse function

  f^-1(x) = (x +4)/3

What 1 7/8 × 2 3/8 will be equal to,greater than or less than 2 3/8
Sunny_sXe [5.5K]

Answer:

greater than

Step-by-step explanation:

Since 2 \frac{3}{8} is being multiplied by a number greater than 1, the result will be greater than 2 \frac{3}{8}

If the multiplier was 1 then the result would be equal to 2 \frac{3}{8}

If the multiplier was between 0 and 1 the result would be less than 2 \frac{3}{8}
