Anywhere there is a point, is part of the domain. So we see a point at x = -2. x = 0, x = 1, x= 2, x = 3, and x = 4.
So the domain would be
{-2, 0, 1, 2, 3, 4}
Answer choice 1.
Answer:
Step-by-step explanation:
let the number =x
then
x²-124=200
x²=200+124
x²=324
x=18
3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
Answer:
f⁻¹(x) = x/4 + 1/2
Step-by-step explanation:
To find the inverse of a function, switch the x and y variables, then isolate y.
f(x) replaced y, so you can replace it back.
y = 4x - 2
x = 4y - 2 Switched x and y
x + 2 = 4y Added 2 to both sides
y = x/4 + 2/4 Divided both sides by 4
y = x/4 + 1/2 Simplified
f⁻¹(x) = x/4 + 1/2 Use function notation
