Question

If f(x) = 5x + 3, then what is f–1(x) ?

Answer 1

inverse

Answer 2

f(x)=y=5x+3

sfr x and then swap x and y

Answer 3

interchange x and y and solve for y

Answer 4

y=5x+3
y-5x=3
-5x=3-y
x=-3/5 - y/3

so

y=-3/5 - x/3

Answer 5

I got x+3/5 as my answer?

Answer 6

\[y=-3/5+1/5\,x\]

Answer 7

I'll draw the options
