Answer:
(x) = √ x + 4
Step-by-step explanation:
step 1) replace f(x) with y
y = x² - 4
step 2) switch the x and y (because every (x, y) has a (y, x))
x = y² - 4
step 3) add 4 to both sides of the equal sign
x + 4 = y²
step 4) take the square root of both sides of the equal sign (the square root symbol cancels out the ²)
√ x + 4 = y
step 5) you know have the inverse of f(x) = x² - 4
(x) = √ x + 4
Answer:
13 divided by 6 divided by 8????? Is that what you're asking?
Step-by-step explanation:
Answer:
it is not a function because the input 5 (x) has more than one output (y)
domain (5,-1,8)
range (2,6,-2,3)
Step-by-step explanation:
Answer is A and B
A) -7.13 < -0.8
B) -0.86 < -0.8
C) -0.79 > -0.8
D) 0.846 > -0.8
Answer:
y=2/7x
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept,
y=2/7x+0
y=2/7x
