Evaluate f(x) = x 2 + 1 for f(10). answers can be: 1. 2√2 2. 101 3. 21

2. 101

You evaluate it using rules.

f(x)=x2+1 for 100 f(10)

so basically you take what x equals on both sides. for usually means apply. so apply what you know. rules properties or give aways.

f(x)=x2+1 for f(10)=101

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
