Question

Solve each function for f(1) please i need help asap

Answer 1

a. 2/3

b.
`√(2)`

c. 3

d. 5

e. 2

f. Undefined

Explanation:

a.
`f(x)=(|x-3|)/(x+2)`

To find f(1), plug in 1 where every x is in the equation

`f(1)=(|1-3|)/(1+2)=(|-2|)/(3)=(2)/(3)`

b.
`f(x) = √(x+1)`

`f(1) = √(1+1)=√(2)`

c.
`f(x) = x^2+5x-3`

`f(1) = (1)^2+5(1)-3=1+5-3=6-3=3`

d.
`f(x)=(2x+3)/(x)`

`f(1)=(2(1)+3)/(1)=(5)/(1)=5`

e.
`f(x) = |2x-4|`

`f(1) = |2(1)-4|=|2-4|=|-2|=2`

f.
`f(x)=(7-2x)/(x-1)`

`f(1)=(7-2(1))/(1-1)=(5)/(0)`

This equation is undefined when x=1 because 0 is the denominator of the fraction.
