Answer: (0,3)
Step-by-step explanation: To find the x-value of the vertex for any quadratic, you can use the formula -b/2a. In this case, there is no clear b, but you can think of it like y=-x^2 +0x+3 so in the form ax^2 + bx +c, b=0. Therefore the x-value is 0/ -2, or 0. So we know the vertex is (0, y). To find y, just plug 0 into the original equation for x, getting you y=0+3, so y=3, so the vertex is (0,3)
Answer:
h = 
Step-by-step explanation:
Given
ba - ha = c ← factor out a from each term on the left side
a(b - h) = c ← divide both sides by (b - h)
a =
Answer:
12/25, 0.25, -6
Step-by-step explanation:
-6 is lower than 0
12/25 is higher than .25 because .25 is 1/4.
Answer:
a=1 is the answer
Step-by-step explanation:
let
p(x)=x³-2ax²+16
put x= -2
p(-2)=(-2)³-2a(-2)²+16
p(-2)=-8+16-8a
p(-2)=8-8a
as (x+2) is a factor of p(x) then p(x) is equal to zero
8-8a=0
8=8a
a=1
