Explain the difference between the graphs of :

charle [14.2K]

Answer:

The only difference is that for any positive value of 'x' g(X) and h(X) will be same and for any negative value of 'x' g(x) and h(x) will be different.

Step-by-step explanation:

Given

$f(x)= |x|$

$g(x) = |x+5|\\\\h(x)= |x| +5$

|x| is modulus of x so modulus makes negative value as psoitive

for example

$|3|= 3$

$|-3|=3$

now we will solve for the above

For $x=4$

$g(4)=|4+5|\\=|9|\\=9$

and

$h(4)=|4| +5\\=4 +5\\=9$

Now for $x=-4$

$g(-4)=|-4+5|\\=|1|\\=1$

and

$h(-4)=|-4| +5\\=4 +5\\=9$

so for positive value it is same and for negative value it is different

Rina8888 [55]

Answer:

15/8

Step-by-step explanation:

Assuming you mean tan theta

Tan(theta) = opposite/adjacent

We know the adjacent side is 8 so the bottom of the fraction must also be 8

C: 15/8 is the only option that fits this criteria
