Curves that share a tangent

Your idea is correct. With a bit different notation we have:

f (x) = x^{2} + 1 g (x) = - 2 x^{2} - 3

As you noted a common tangent is a line that passes thorough the points:

(x_{1}, f (x_{1})) (x_{2}, g (x_{2}))

Find inverse of

You wrong in saying that

[42]_{5} = [- 2]_{5}

x

correctly, since

[42]_{5} [- 2]_{5} = [2]_{5} [3]_{5} = [6]_{5} = [1]_{5}

, although since we are working mod 5 it is traditional to choose the representative ...

2^{∣ x + 2 ∣} - ∣ 2^{x + 1} - 1 ∣ = 2^{x + 1} + 1

https://math.stackexchange.com/questions/2807159/solve-2x2-2x1-1-2x11

x < - 2

, the equation becomes

2^{- (x + 2)} + 2^{x + 1} - 1 = 2^{x + 1} + 1

2^{- (x + 2)} = 2

- (x + 2) = 1

x + 2 = - 1

x = - 3

x \geq - 1

2^{x + 2} - 2^{x + 1} + 1 = 2^{x + 1} + 1

2^{x + 2} = 2 \cdot 2^{x + 1} = 2^{x + 2}

Chia sẻ

Đã sao chép vào bảng tạm

x=\frac{-2}{2}

Chia cả hai vế cho 2.

x=-1

Chia -2 cho 2 ta có -1.
