Question

consider the following function. f(x)=4x+7. Place the steps for finding f-1(x) in the correct order (photo)

Answer 1

Step-by-step explanation:

f(x)=4x+7

y = 4x+7

4x = y-7

x = (y-7) /4

the correct answers are:

=> f`¹(x) = (x-7) /4 (a)

=> x - 7 = 4y (e)

=> (x-7) /4 = y (f)

=> x = 4y +7 (g)

Answer 2

Answer:

$f(x) = 4x + 7 \\ y = 4x + 7 \\ 4x = y - 7 \\ x = \frac{y - 7}{4} . \\ \\ the \: correct \: answers \: are \: \\ \\ f {}^{ - 1} (x) = \frac{(y - 7)}{4(a)} . \\ x - 7 = 4y(e). \\ \frac{(y - 7)}{4} = y(f). \\ x = 4y + 7(g).$
