<u>Solution for question 5:</u>
f(x) = 4x - 8
To find f^-1(x) write it as an equation:
y = 4x - 8
Then take x to left and y to right;
x = 4y - 8
Then solve for y;
y = (x + 8)/4 = x/4 + 2
Your y is the inverse of f(x) = 4x - 8
f^-1(x) = x/4 + 2
Answer:
89
Step-by-step explanation:
100/36= 2.77777778
2.77777778·32 = 88.8888889
89
So you would act like it was an equal sign and solve it like normal. Subtract 45 from both sides. Get 14"="2x. Divide by 2 and get 7 >x. If you were to multiply or divide by a negative than you would flip the sign, but you leave it in this case because you divided by a positive. I hope that helps.
