Answer:
Step-by-step explanation:
There is no pictures to choose the right one among tem.
However the equation could be rewritten as follows:
y=√(x²-9)
It is a HORIZONTAL parabola with the following constraint: 3=<x=<-3
Answer:
B
Step-by-step explanation:
f(x) = y = x^2 + 7
x = y^2 + 7
x - 7 = y^2
sqrt(y^2) = sqrt(x - 7)
y = +/- (x - 7)
Answer B
Answer:
the number = 8/5 or 1 3/5 or 1.6
Step-by-step explanation:
n = the number
5/2n - 11 = 4
5/2n - 11 + 11 = 5 / 2n
5/2n = 4
5/2n / 5/2 = n
4 / 5/2 = 8/5
