Hello,
The graph of y = x² + 1 most certainly is a function.
It is a function because for every value of x, there is only one value of y.
The domain of y = x² + 1 is the set of all real numbers and the range is y ≥ 1.
I think A bc it looks like ur saying -4 and -3 but if they are positive then it’s D
Answer:
E (-2, 4).
Step-by-step explanation:
(x/2 + 1)(x/2 - 2) = 0
x/2 = -1, x/2 = 2
x = -2, 4.
The roots will be 2 times the roots of f(x).
Answer:
x=30
Step-by-step explanation:
4x+2x=180
6x=180
x=30
Answer:
900
Step-by-step explanation:
Assume x brick
X*(1／9+1/10）一 10=X/5
X(19/90-1/5)=10
X*(1/90)=10
X=900
