To get the inverse, first off do a quick switch on the variables, and then solve for "y".
The first one is correct because the angle on the opposite side is the same, and the second one is correct too because it's the same points. So you can pick either or.
Problem
evaluate the function
f(-x) = f(x)
plug in the points (2,1) then solve
Solution
For this case we can conclude that:
f(2) =1
So then we satisfy that:
f(-2) =1
Answer:
7/12
Step-by-step explanation:
2 1/3 + 1 3/4
7/3 + 7/4

Answer: x = -2, y = -10
Step-by-step explanation:
solve for x first in the equation -2x+3=7
-2x+3=7
-2x = 4
x = -2
now plug that x value into the other equation so we can find y
3x+1 = 5+y
3(-2)+1 = 5+y
-6+1 = 5+y
-5=5+y
-10 = y
