This week we have been doing everything related to inequalities.

We first started with graphing linear inequalities. For this we returned to the idea of graphing regular linear equations.

If we take a look at the equation y=x-2 we know that the slope is 1/1 and the y-intercept is -2

Q1.) y ≥ 3x² – 4

a.) (–3,8)

Ans.) 3(–3)² –4

27–4

y≥23

b.) (0,5)

Ans.) y≥3(0)²–4

5≥0–4

c.) (4,44)

Ans.) 44 ≥ 48 –4

44≥44
