The function p(x) = x^3 is a polynomial. Here the “variable”, x, is being raised to some constant power. The function f(x)=3^x is an exponential function (the variable is the exponent).
Exponential functions tend to get very big very quickly, and though they start out smaller than polynomial functions, they will always eventually become bigger. Notice that the two functions meet at x = 2 and x = 4.
Answer:
A. x + y = 4000
5x + 3y = 15000
Step-by-step explanation:
Total amount raised = $15000
cost of adult tickets = $5
cost of student tickets = $3
Total number of tickets sold = 4000
number of adult tickets sold = x
number of student tickets sold = y
Then we can say,
total number of ticket sold = number of adult tickets + number of student tickets
4000 = x + y
⇒ x + y = 4000 ............. 1
Also,
5x + 3y - 15000 ............. 2
the equations required are:
x + y = 4000
5x + 3y - 15000
Answer:
-74
Step-by-step explanation:
f(x) = -2x^2 +8x -10
Let x = -4
f(-4) = -2 ( -4)^2 +8(-4) -10
= -2(16) -32-10
= -32 -32-10
= -74
