Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1). (1 point)
mylen [45]

Answer:

-6

Step-by-step explanation:

Hope I understand your "f(x) = 12 over the quantity of 4 x + 2" correctly

f(x) = 12 / 4x +2

Now so they want a f(-1), as u can see they substituted the x for - 1, therefor do that the same to the right side

f(-1) = 12/ 4(-1) + 2

f(-1) = 12 / - 4+2

= 12/ - 2

= - 6

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
