Answer:
B
Step-by-step explanation:
Substitute the x value into the right side of the function and if the value obtained is equal to the y value of the point then it is a solution.
(0, - 4) → y = 5(0) - 4 = 0 - 4 = -4 ← True
(2, 6) → y = 5(2) - 4 = 10 - 4 = 6 ← True
(4, 20) → 5(4) - 4 = 20 - 4 = 16 ← False
(4, 16) → 5(4) - 4 = 20 - 4 = 16 ← True
(0, - 4), (2, 6), (4, 16) ← possible inputs and outputs
Answer:
Step-by-step explanation:
f * g = (x^2 + 3x - 4) (x+4)
open bracket
x((x^2 + 3x - 4) + 4 (x^2 + 3x - 4)
x³ +3x²-4x+x²+12x-16
x³+3x²+x²-4x+12x-16
x³+4x²+8x-16 (domain is all real numbers.
f/g = (x^2 + 3x - 4)/(x+4)
factorising (x^2 + 3x - 4)
x²+4x-x_4
x(x+4) -1 (x+4)
(x+4)(x-1)
f/g = (x^2 + 3x - 4)/(x+4) =(x+4)(x-1)/(x+4) = (x-1)
Before factorisation, this was a rational function so the domain is all real numbers excluding any value that would make the denominator equal zero.
Hence I got x - 1, and x cannot equal -4
So the domain is just all real numbers without -4
D. 50. Since WZ is perpendicular, it has a right angle plus the 40 degrees given at V equals 130. Add 50 to get 180.
Answer: Option 'E' is correct.
Step-by-step explanation:
Marginal utility is the addition utility derived from each successive unit of a particular good.
so, marginal utility is the change in utility from consuming an addition unit of a good or service.
Mathematically, it is expressed as
Hence, Option 'E' is correct.
