Answer:
f inverse x = -x+4/5
Step-by-step explanation:
Given:
The equation of the parabola is:
To find:
The y-intercept of the parabola.
Solution:
We have,
Putting 
in the given equation, we get
Therefore, the y-intercept of the parabola is 0. It means the y-intercept of the given parabola is at point (0,0).
Answer:
The answers are 3z-16 and 2z+10
Step-by-step explanation:
Do 3 x z (3z) and then do 3 x 4 (16) and then you got 3z-16
Do 2 x z (2z) and then do 2 x 5 (10) and then you got 2z + 10
The answer to that would just be 18 if you want the word in number form, I'm actually kinda confused on what your question means
I think it is the last one because 5/1 × 4/4 = 20/4 or 5
