Answer:
hg
Step-by-step explanation:
Don't report what you don't understand
the x value of the vertex of the parabola in form
y=ax^2+bx+c
is -b/2a
given
y=6x^2-72x+220
x value of vertex is -(-72)/(2*6)=72/12=6
xvalue is 6
sub that for x in the equation
y=6(6)^2-72(6)+220
y=216-432+220
y=4
(x,y)
vertex is (6,4)
12 and 24
The equation is 2x + x =36
So 3x = 36
Then divide each side by 3
So x =12
That is the smaller number
Multiply it by 2 to get the bigger number since it's twice the number
Answer: f(x) = x²
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: f(x) = a(x - h)² + k where;
- |a| is the vertical stretch
- -a is a reflection across the x-axis
- (h, k) is the vertex
The parent function is where a = 1 and the vertex is at the origin <em>(h, k) = (0, 0)</em>
→ f(x) = 1(x - 0)² + 0
⇒ f(x) = x²
