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 =
- 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
Answer:
positive integers = x
4.9 < x < 10.1
x = 5, 6, 7, 8, 9, 10
sum = 5 + 6 + 7 + 8 + 9 + 10
= 45
