Answer:
and 
Step-by-step explanation:
To find the inverse, we will set f(x) equal to y, swap the x and y values, and then solve for y.
Given:
f(x) = x² - 25
Equal to y:
y = x² - 25
Swamp x and y values:
x = y² - 25
Add 25 to both sides of the equation:
y² = x + 25
Square root both sides of the equation:

Interval notation:

Answer:
3/4
Step-by-step explanation:
tan theta = opposite side/ adjacent side
tan A = 3/4
Answer:
no it is not. it would be an equilateral triangle because each side is the same length
