Graph the function fx 4 10 and answer the following questi
Graph the function, f{x) = -4 + 10 and answer the following question Find the domain of f. (Enter your answer using interval notation.) Find the range of f. (Enter your answer using interval notation.)
Solution
given f(x) = -4 | x-25 /10 | + 10
so domain is all the values (-infinite , infinite)
since domain means all the values \'x\' can take
here we have mod (x-25/10) it can take all real values
so domain is R
and range is all the f(x) values
-4| x-25 /10| will give all negative values
-4| x-25 /10| +10 will have a max of 10 value
so range is (-infinite , 10)
c). f(5)
plug x=5
so f(5) = -4 | 5 -25 /10 | +10
= -4 | -20/10| + 10
= -4 |-2| +10
= -4 *2 +10
= -8 +10
= 2
