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
if the number of boys is x ,then the number of girls is x+7,so 2x+7=35,we can know x=9,so the number of boys is 9,and girls are 16
and
If we want to express as , this means that put the function into of to get .
The function is given as
<u>So we need to figure out a function that we can put into another to get </u>
If we let and , we can clearly see that putting g(x) into x of f(x) will give us , which is y.
Hence and
