Answer:
Hello first one is 4.
Second one is 8
Step-by-step explanation:
First one is f(0). It means you should put zero in the place of x
0 is less than 5 so you should put zero in x+4=f(x)
For the second one do like the first one.
I hope you understand
Answer:
7 + 3x ≥ 13
Step-by-step explanation:
The best way to write this is to truly understand what each of the terms mean. The sum means that multiple terms are added together, which means that 7 and 3 times a number will be added together.
Next, the term three times a number just means 3x. So as of now, we have 7 and 3x being added together.
Finally, the term at least 13 means that the 7 + 3x is greater than or equal to 13. Once everything is put together, you get a final inequality of 7 + 3x ≥ 13.
Answer:
0 and 2
Step-by-step explanation:
To find zeros set f(x)=0 and solve for x
now factor out x
set each factor =0 and solve for x
no solution for x
zeros of f are 0 and 2
