Answer
Find out f(f(x)) .
To prove
As given in the question
f(x) = x² + 1
Now
f(f(x)) = f (x² + 1)
Now find out the value of f (x² + 1).
f(f(x)) = f (x² + 1)
= (x² + 1)² + 1
Using formula
(a + b)² = a² + b² + 2ab
Apply in the above function
f(f(x)) = (x² + 1)² + 1
Simplify
Thus the value of f(f(x)) is .
Answer:
-18

Answer:
<h3>
<u>
x = -7</u></h3>
Step-by-step explanation:
x-coordinate of both points is the same. That means the line is parallel to Y-axis
Equation of every line parallel to Y-axis is: x = x₀
where x₀ is the x-coordinate of any point from the line
x₀ = -7 so the equation is:
<u>x = -7</u>
5(x + 2) + 6(x - 3) = 25
Simplify.
5x + 10 + 6x - 18 = 25
Add like terms.
(5x + 6x) + (10 - 18) = 25
Simplify.
11x - 8 = 25
Add 8 to both sides.
11x = 25 + 8
Simplify.
11x = 33
Divide both sides by 11.
x = 3
~Hope I helped!~
-4x + 8y = 2
-4x + 4x + 8y = 2 + 4x
8y = 4x + 2
8 8
y = ¹/₂x + ¹/₄
