Answer:
f(f(x)) = 27 + 18x² + 4
Step-by-step explanation:
To find f(f(x)) substitute x = f(x) into f(x) , that is
f(3x² + 1)
= 3(3x² + 1)² + 1 ← expand parenthesis using FOIL
= 3(9 + 6x² + 1) + 1 ← distribute parenthesis by 3
= 27 + 18x² + 3 + 1 ← collect like terms
= 27 + 18x² + 4
Answer:
(0,-41)
Step-by-step explanation:
Let see if this table of values are proportional.
- All x values decrease by -9.
- All y values decrease by -19.
This mean that the function is proportional. This also gives us the slope which is 19/9.
This tell us that this function will be a linear function since we are trying to find the y intercept we would use this equation
We know the slope and we know a point so let use point slope form to find the intercept.
Let use points (-18,-79) and let m =19/9.
This is in slope intercept form so the y intercept is
The answer is -41.
