Answer:
<em>f(10)=290</em>
Step-by-step explanation:
<u>Function Evaluation</u>
Given a function f(x) as an explicit expression, finding f(x=a) implies substituting the value of x by a in every instance it occurs.
We are given the function:
It's required to find f(10). We replace the x for 10:
Operating:
Thus, f(10)=290
Answer:
first answer.. make an induction
Answer:
y = (x - 3)² - 3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
add/subtract (half the coefficient of the x- term )² to x² - 6x
Given
y = x² - 6x + 6
= x² + 2(- 3)x + 9 - 9 + 6
= (x - 3)² - 3 ← in vertex form
Answer:
.05 kilometers
Step-by-step explanation:
One kilometer is 1000x more than a single meter. And 
.
Using a sample inequality, take 35> ? + 3. Making that ?=x, we have 35 > x+3. Subtracting 3 from both sides, we get 32 > x. Therefore, as long as 32 is greater than x, any value replacing x is fine.
I challenge you to apply this strategy to this problem! Good luck, and feel free to ask with any questions!
