The function f(x) is shown on the graph. What is f(0)?

x = -2, -1 ,1 ,3

Step-by-step explanation:

We want to find when the graph has a y value of 0

There are 4 values where this occurs

x = -2, -1 ,1 ,3 is when the y value is 0

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
