Use Pythagorean theorem to solve.
a^2 + b^2 = c^2
6^2 + b ^2 = 14^2
36 + b^2 = 196
Subtract 36 from both sides.
b^2 = 196-36
b^2 = 160
Take the square root of both sides.
b = sqrt 160
As a decimal
b = 12.649
As a simplified radical
b = 4sqrt10
Answer:
f(x) = -(x-4)² + 5
Step-by-step explanation:
f(x) = -(x-4)² + 5
Has a maximum vertex at (4,5)
Which means the function has a greatest value of 5 at x = 4
Therefore the range is:
y《5
