Answer:
Step-by-step explanation:
A function
is the inverse of f if whenever y =f(x) and
To find the inverse of f(x) =
- 5, we use the following steps:
- Step 1 : Put y for f(x) and solve for x
y =
- 5
<=>
= y + 5
<=> x = ![\sqrt[3]{y+ 5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%2B%205%7D)
- Step 2: Put
for x, we have:
- Step 3: Interchange y =x, we have
Let Calculate 3 points on f(x)
x = 0 => y = -5
x = 1 => y = -4
x = 2 => y = 3
Let Calculate 3 points on
(x)
x = -5 => y = 0
x = -4 => y = 1
x = 3 => y = 2
Yes, the inverse is correct because:
- the domain of the inverse function is the range of the original function
- the range of the inverse function is the domain of the original function
1/4 hour is the same as 15 minutes. If it takes 15 minutes to paint 1/3, then it would take 45 minutes to paint the whole wall.
Answer:
2x-30
Step-by-step explanation:
5(x-3) = 5x-15
-3(x+5) -3x-15
(5x-15) + (-3x-15) = 2x-30
