Find the average rate of change for f(x) = x2 + 9x + 18 from x = -10 to x = 10.
Ratling [72]
With the way the equation is written, we can assume that the “x2” is x multiplied by 2.

The x2 and 9x are like terms, and can be simplified to 11x.

Our new equation is
f(x) = 11x + 18

With no exponential functions in the equation, the difference of each value’s output would be 11.

Find the smallest value of $x$ such that $x^2 + 10x + 25 = 8$.
Mashutka [201]

Answer:

-5 -√8  or ≈ -7.83

Step-by-step explanation:

<u>Solving the quadratic equation, to find its roots:</u>

  • x^2 + 10x + 25 = 8           ⇒ The left side is perfect square
  • (x+5)^2=8                         ⇒ Getting square root of both sides
  • x+5 = ± √8                       ⇒ There are 2 roots
  • x = - 5 ± √8

<u>The smallest root is:</u>

  • x= -5 - √8 ≈ -7.83
