m = (-1 - 4) /(2-3) = -5/-1 = 5
slope = 5
passing (3, 4)
y = mx + b
4 = 5(3) + b
4 = 15 + b
4 -15 = b
-11 = b or b = -11
answer:
equation
y = 5x - 11
If the equation is x/(x^2-4) then I will solve it here
it's rational
therefor we can't have any impossibles like dividing by zero and square root of -1 an d stuff
f(x)=x/(x^2-4)
we know that the denomenator cannot be equal to zero so the numbers you cannot user are the numbers that will make the bottom number zero
so x^2-4=0
x^2=4
x=-2 or 2
so x cannot be -2 or 2, but it can be all other numbers so
domain=all numbers except -2 and 2
Answer:
Under the geometric expression. We have something SOH CAH TOA ie
SOH means Sin x = opposite/Hypothesis
CAH means Cos x = Adjacent/Hypothesis
TOA means Tan x = Opposite/Adjacent
So from the diagram the proper formula for this question is TOA
Tan x = Opposite/Adjacent
Tan x = 15/48
Tan x = 0.3125
x = tan^-1 (0.3125)
Step-by-step explanation:
The general form of the function is
where
A = amplitude
T = period
φ = phase shift.
Given:
A = 3
T = 4π
φ = -π
