What is the y-value of the vertex of the function f(x) = –(x + 8)(x – 14)?
1 answer:
we have

Convert to vertex form

we know that
the equation of a vertical parabola in vertex form is equal to

where
(h,k) is the vertex

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Complete the square. Remember to balance the equation by adding the same constants to each side


Rewrite as perfect squares


the vertex is the point 
therefore
<u>the answer is </u>
The y-value of the vertex is

Answer: Where is the work??
Step-by-step explanation:
This means which transformation makes the same answer at x = 0
f(x) = 3x + 4

f(0) = 4
g(0) = 1 - 1 = 0
Which transformation makes 4 = 0?
4 + x = 0 + y
4 - 3 =0 + 1
1 = 1
Option 1 is your answer
Answer:
x≤10
Step-by-step explanation:
2x-15≤5
+15 (both sides)
2x≤20
divided by 2 (both sides)
x≤10
