Question

1. solve inequiality 20-3x>14. Graph the solution set.

2. The graph of a function y=f(x) always crosses the y-axis. True or False
3. every graph represents a function.
A. the statement is true because every graph associates a unique x-value for each y-value
B. the statement is true because every graph associates a unique y-value for each x-value
C. the statement is false because a graph that crosses the x-axis two times does not represent a function
D. the statement is false because a graph that crosses the y-axis two times does not represent a function
4. the inequality-15. i need help to do that from 31 to 66. Thank you so so much ❤️. I just can’t do simple things. I need to step by step calculate solutions. Because i know which one is equation or not but didn’t know how to solve
