Step-by-step explanation:
To find f(4), you must substitute 4 in place of x whenever x appears:
f(x) = *
f(4) = *
Next, simplify the exponent:
f(4) = * 256
Finally, multiply:
f(4) = 85 1/3 or 85.333...
Answer:
X = 9 months
Step-by-step explanation:
To solve the number of months when the cost of each payment
are the same, you should equate the two cost. First establish the equations
Let A be the cost of first payment method
B is the cost of the second payment method
X is the number of months
A = 38x + 15
B = 31x + 78
38x + 15 = 31x + 78
7x = 63
X = 9 months
