f(x)=-x²-2x-8 determine the vertex
Answers
Answer:
vertex = (- 1, - 7 )
Step-by-step explanation:
Given a parabola in standard form, f(x) = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
f(x) = - x² - 2x - 8 ← is in standard form
with a = - 1 and b = - 2, then
[tex]x_{vertex}[/tex] = - [tex]\frac{-2}{-2}[/tex] = - 1
Substitute x = - 1 into f(x) for corresponding y- coordinate
f(- 1) = - (- 1)² - 2(- 1) - 8 = - 1 + 2 - 8 = - 7
vertex = (- 1, - 7 )
We can use a shortcut such that:

The curve with equation y = x^2 + ax + 3 has a stationary point when x = 4. Find a.
Answers
Answer:
Step-by-step explanation:
y=x^2+ax+3
y=(4)^2+a(4)+3
y=16+4a+3
y=19+4a
y-19=4a
y-19/4=a
a=y-4.75

Answers
Answer:
x = - 9
Step-by-step explanation:
Given
- (5x - 4) = 49 ← distribute the parenthesis by - 1
- 5x + 4 = 49 ( subtract 4 from both sides )
- 5x = 45 ( divide both sides by - 5 )
x = - 9
