sqrt(0.5x^2)+1<= 4|x|

Solution

0.5 x^{2} + 1 \leq 4 ∣ x ∣

Solution

x \leq - 0.30368 \dots or x \geq 0.30368 \dots

+1

Solution steps

0.5 x^{2} + 1 \leq 4 ∣ x ∣

Subtract

1

from both sides

0.5 x^{2} + 1 - 1 \leq 4 ∣ x ∣ - 1

Simplify

0.5 x^{2} \leq 4 ∣ x ∣ - 1

If

f (x) \leq g (x)

then

g (x) \geq 0

4 ∣ x ∣ - 1 \geq 0 : x \leq - \frac{1}{4} or x \geq \frac{1}{4}

0.5 x^{2} \leq 4 ∣ x ∣ - 1 : x \leq - 0.30368 \dots or - 0.21244 \dots \leq x \leq 0.21244 \dots or x \geq 0.30368 \dots

Verify Solutions:

x \leq - 0.30368 \dots

True

, x \geq 0.30368 \dots

True

The solution is

x \leq - 0.30368 \dots or x \geq 0.30368 \dots
