Answer:

a.f(-1)=2

b.f(3)=6

c. f(x-1)=x+2

Step-by-step explanation:

We are given that f(x)=x+1+2

a.We have to find the value of f(-1)

Substitute the value of x in the given function

Then, we get

f(-1)=-1+1+2=2

f(-1)=2

b.We have to find the value of f(3)

Substitute x=3 then we get

f(3)=3+1+2=6

f(3)=6

c.We have to find the value of f(x-1)

Replace x by x-1 then we get

f(x-1)=x-1+1+2=x+2

Hence, f(x-1)=x+2

What is 3 1/4 divided by 2/3 with all of the steps?
erik [133]

Answer:

4 7/8

Step-by-step explanation:

3 1/4 / 2/3

convert mixed numbers to improper fractions: 3 1/4 / 2/3

13/4 / 2/3

apply the fraction rule: a/b / c/d = a/b * d/c

= 13/4 * 3/2

multiply fractions: a/b * c/d = (a * c)/(b * d)

= (13 * 3)/(4 * 2)

multiply the numbers: 13 * 3 = 39

= 39/(4 * 2)

multiply the numbers: 4 * 2 = 8

= 39/8

convert improper fractions to mixed numbers: 39/8 = 4 7/8

= 4 7/8
