f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
The answer would be y=4x-18.
Answer:
Zero is not a natural number
Step-by-step explanation:
Hope this helps!
Consider each polynom separately:
1)
Since
, then
.
2)
.
Then
.
Similarly,3)
and
4)
Then
.
Now multiplication becomes easier:
You obtain answer
, where
a=1, b=9, c=2, d=-4.
That's what it will look like
