It is correct!!
Step-by-step explanation:
Answer:
- y-intercept: (0, 3)
- axis of symmetry: x = -1
Step-by-step explanation:
The y-intercept is the constant, 3. It is the value of f(0).
__
The axis of symmetry of the quadratic function ...
f(x) = ax^2 +bx +c
is ...
x = -b/(2a)
Here, using that formula gives ...
x = -(2a)/(2(a)) = -1
The axis of symmetry is x = -1.
Answer:
4-2=2 6^2=36
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
6²+8²
=100
√100
=10
A²+b²=c²
39²+b²=89²
1521+b²=7921
subtract 1521 from both sides
b²=6400
so then you square both sides
√6400
