Question

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

Answer 1

Answer:

a. 2/3

b. $\sqrt{2}$

c. 3

d. 5

e. 2

f. Undefined

Step-by-step explanation:

a. $f(x)=\frac{|x-3|}{x+2}$

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

$f(1)=\frac{|1-3|}{1+2}=\frac{|-2|}{3}=\frac{2}{3}$

b. $f(x) = \sqrt{x+1}$

$f(1) = \sqrt{1+1}=\sqrt{2}$

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

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

d. $f(x)=\frac{2x+3}{x}$

$f(1)=\frac{2(1)+3}{1}=\frac{5}{1}=5$

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

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

f. $f(x)=\frac{7-2x}{x-1}$

$f(1)=\frac{7-2(1)}{1-1}=\frac{5}{0}$

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