Step-by-step explanation:

Solution:-

- Here we will take a look at the effect of translation on the original graph.

- Where, f(x) is the original given function which undergoes translation ( up, down, right or left ) and result in g(x).

- The general form of all possible translations are given:

Vertical Translation

                         g ( x ) = f(x) + a

Where,   a > 0 number of units the f(x) moves up

              a < 0 number of units the f(x) moves down

Horizontal Translation

                         g ( x ) = f ( x + b )

Where,   b > 0 number of units the f(x) moves left

              b < 0 number of units the f(x) moves right

part a)

                        f ( x ) = x

Where, f(x) undergoes a vertical translation of 7 units up.

So using the first case with value of a = +7

                        g ( x ) = f(x) + 7

                        g ( x ) = x + 7

part b)

                        f ( x ) = x^2

Where, f(x) undergoes a horizontal translation of 5 units left.

So using the second case with value of b = +5

                        g ( x ) = f(x + 5)

                        g ( x ) = ( x + 5 )^2

part c)

                        f ( x ) = x^2

Where, f(x) undergoes two translations; horizontal translation of 3 units right and a vertical translation of 4 units up .

So using the first and second case with value of a = + 4 , b = -3

                        g ( x ) = f(x - 3 ) + 4

                        g ( x ) = ( x - 3 )^2 + 4

part d)

                        f ( x ) = absolute (x)

Where, f(x) undergoes two translations; horizontal translation of 1 unit left and a vertical translation of 5 units down .

So using the first and second case with value of a = - 5 , b = +1

                        g ( x ) = f( x + 1 ) - 5

                        g ( x ) = absolute [( x + 1  )] - 5

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
