Answer:
Emily solved for a part when she should have solved for the whole. 875,000 should be the numerator of the equivalent ratio. 70 x 12,500 is 875,000. So the answer is 100 x 12,500 which is 1,250,000.
Step-by-step explanation:
The inverse of the function f(x) is x/4 + 3/28
The function is given as:
f(x) = 4x - 3/7
Set f(x) = y
y = 4x - 3/7
Swap the positions of x and y
x = 4y - 3/7
Make y the subject
4y = x + 3/7
Divide by 4
y = x/4 + 3/28
Hence, the inverse of the function f(x) is x/4 + 3/28
