What function is shown in the graph?

a) y = -2x

b) y = 2-x

c) y = 2x – 5

d) y = 2x – 5

Step-by-step explanation:

The parent function of the given graph is y=2^x because all the given options have basic exponent 2^x

LEts take the basic function as

To find the value of 'a', pick a point from the given graph

LEts pick (0,-1), plug in the values and find out 'a'

a=-1

The equation becomes

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
