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:
and
Interval notation:
Use trigonometry ratio to solve the problem, the ratio we use is tan ratio
tan α =
plug in the numbers to find α
tan α =
tan α =
tan α =
tan α = 1.25
α = tan⁻¹ (1.25)
α = 51.340...
α = 51.3
