Sum of a number, n and 21...." the sum " means add
n + 21
if n = 8
8 + 21 = 29....the sum is 29
Answer:
Domain: (-∞, ∞)
Range: [0, ∞)
Step-by-step explanation:
The domain represents what x can be. In this scenario, we do not have x as a denominator, and there is nothing limiting x, so its domain is (-∞, ∞)
The range represents what f(x) can be, Because |x-4| is in absolute value, the lowest |x-4| can be is 0, and as a result, the lowest value of 2|x-4| is 2*0=0. The maximum value of f(x) is ∞ as an absolute value does not limit the maximum, making the range [0, ∞)
The total cost that will be paid by the family will be RM(15x - y).
<h3>How to calculate the cost?</h3>
The entrance fee to a circus for a child is RM(3x-y).
The entrance fee for an adult is RM(3x - y) + RM2y = 3x + y.
Therefore, the cost for 2 adults and three children will be:
= 2(3x + y) + 3(3x - y)
= 6x + 2y + 9x- 3y
= 15x - y

Therefore,
Option a is "True".
Option b is "True".
Option c is "True".
Option d is "False".
Option e is "False".
Option f is "True".
Answer:
f(3) = -20
Step-by-step explanation:
To find the value of a function, substitute the number for the variable and do the arithmetic.
f(x) = -2x^2 +x -5 . . . . . . given
f(3) = -2(3^2) +(3) -5 . . . . function value for x = 3
f(3) = -2(9) +3 -5 = -18 +3 -5
f(3) = -20
