Answer:
-4
Step-by-step explanation:
Answer:
f(x) = 3^x increases steadily on the interval [4,5].
Step-by-step explanation:
This exponential function f(x) = 3^x has a positive base (3) which is larger than 1. Thus, this function continues to increase as x increases, including the case where x increases from 4 to 5.
We can just plug in the values of x = 2 and y = 4 into the expression 4x+y to get 4*2 + 4 = 8 + 4 = 12.
for 2y-x = 2*4 - 2 = 8 - 2 = 6
