Hi there I need help with these questions !

Let f(x) = 2" and g(x) =() . and evaluate the following: 9( - 3) - 9(3) -3 -3 Preview Let f(x) = 3" and g(z) = in 1 (0/1) and evaluate the following: in 2 (0/1) on 3 (0/1) f(z) - f( - 2) on 4 (0/1) I - (- 2) Preview syntax error Let f(x) = 3" and g(z) = , and evaluate the following: g(z) - 9(2) Preview TIP Suppose it takes 6 hours for a certain strain of bacteria to reproduce by dividing in half. If 60 bacteria are present to begin with, the total number present after a days is f(x) = 60 - 16. Find the total number present after 1, 2, and 3 days. There will be bacteria present after 1 day, after 2 days and after 3 days. The declining-balance method of depreciation is an accounting method businesses use to deduct most of the cost of new equipment during the first few years of purchase. Unlike other methods, the declining-balance formula does not consider salvage value. For the value of a crane, the function V(t) = 550000(1 - 0.3), where V is value and t is time in years, can be used to find the value of the crane for the first 7 years of use. a. What is the value if the crane after 2 years and 9 months? The value of the crane will be $ b. State the domain of the function. c. State the range of this function. As a car ages, its value decreases. The value of a particular car with an original purchase price of $26, 200 is modeled by the following function, where c is the value at time t, in years. c(t) = 26, 200(1 - 0.22) a. What is the value of the car when it is 4 years old? The value of the car after 4 years is $ b. What is the total depreciation amount after 5 years? After 5 years, the total depreciation amount is S Graph the function: y = 3 TO -2 Let f(x) = 4". Evaluate the following: C /1) f(3 ) - f( - 1 ) 3 - (-1) Preview D/1) TIP
