Answer:
Equation of function, y = (x-1)²
Step-by-step explanation:
The general formula of a parabola symmetric about x - axis is given by (x-h)²=4a(y-k), where (h,k) is the vertex.
Here (h, k) = (1,0)
So, we have (x-1)²=4a(y-0)
(x-1)²=4ay
One point on the parabola is (0,1) since y intercept is 1.
Substituting
(0-1)²=4 x a x 1
1 = 4 a
Equation of parabola,
Equation of function, y = (x-1)²
Answer:
B
Step-by-step explanation:
Using the quadratic formula with
a = 16, b = 0 and c = - 80, then
x = ( 0 ± / 32
= ±
x = - , x =
x = - 2.24, x = 2.24 ( to the nearest hundredth )
