Write a function in function notation and use the function to solve the problem 4. A cordless phone costs $55 plus $25 for each extra handset. What is the cost of a cordless phone and 3 extra handsets? dollars $ 130 functions y = 25 * + 55 120 Evaluate the function using function notation and interpret the value in context. In 2019, a science class is reading an article on global temperatures on the earth observatory page from NASA A student determined the predicted global temperature in Celsius by the decade is equal to the function f(d) = .20d + 14, where d is the number of decades. 5. What is the value of f (d) at f (10)? f( 10) = 16 6. What is the value of f (10) in context? Fill in the blank. In 10 decades, the predicted global temperature will be Celsius. 7. Based on the context, which statement is true. Select one. A. The number of decades d, depends on the global temperature f (d). B. The global temperature f (d) depends on the number of decades d. 0 C. The global temperature d depends on the number of decades f(d). 8. Joe wants to grow a habanero plant from a seed. He measured the height of his plant each day for 30 days. After measuring his plant for 30 days, he determined the height of the plant in centimeters is equal to the function f(t), where f(t) = 0.2t where t is the number of days that have passed since the seed was planted. What is the value of f (40). f(40) = What is the value of f(40) in context
