If f(x)= x2/x+3, find f(x+h)?
kompoz [17]

f(x+h) =  \frac{x^{2}+2xh+h^{2}  }{x+h+3}

Step-by-step explanation:

Given,

f(x) = \frac{x^{2} }{x+3}

To find the value of f(x+h) we need to replace x by x+h

Hence,

f(x+h) = \frac{(x+h)^{2} }{x+h+3}

= \frac{x^{2}+2xh+h^{2}  }{x+h+3}

[Here, we apply the formula of (a+b)^{2}= a^{2} +2ab+ b^{2}]

BRAINLIEST!!! I need help ASAP how do I find the percent change from 1960 to 2000
SVEN [57.7K]

Answer:

percentage change  from 1960 to 1970 =( 0.11 ÷0.25 ) × 100

                                 = 44 %  

Percentage change from 1970 to 1980 =( 0.83 ÷ 0.36) × 100

                                                                 = 230.55%

 percentage change from 1980 to 1990 = ( 0.16 ÷ 1.19) × 100

                                               = 13.44%

percentage change from 1990 to 2000 = (- 0.09 ÷ 1.35) × 100

                                             = -6.667%                                              

Step-by-step explanation:

Item : 1960      1970          1980           1990             2000

gallon: $0.25  $0.36        $1.19    $1.35                 $1.26

change : 0.36 - 0.25 = 0.11

percentage change  from 1960 to 1970 =( 0.11 ÷0.25 ) × 100

                                 = 44 %

 Percentage change from 1970 to 1980 =( 0.83 ÷ 0.36) × 100

                                                                 = 230.55%

 percentage change from 1980 to 1990 = ( 0.16 ÷ 1.19) × 100

                                               = 13.44%

percentage change from 1990 to 2000 = (- 0.09 ÷ 1.35) × 100

                                             = -6.667%
