For an exponential regression equation in the form y=ab^x which of the following values of b will cause y to get smaller as x ge

sdas [7]

Answer:

d) 0.798

Step-by-step explanation:

Since we know that an exponential function is in form: $y=a*b^x$ , where,

a= Initial value,

b = For growth b is in form (1+r), where r is rate in decimal form.

b = For decay or regression b is less than 1 and in form (1-r), where r is rate in decimal form.

Upon looking at our given choices we can see that options a, b and c are in form 1+r, while choice provided in option d is less than 1 and in form 1-r, therefore, option d is the correct choice.

Split it up into 3 separate shapes.

Rectangle 1 = 15 x 3 = 45

Rectangle 2 = 3 x 5 = 15

Triangle = 1/2 x 5 x 3 = 7.5

Total area = 45 + 15 + 7.5 = 67.5 cm²
