Answer:
Vertical.
Step-by-step explanation:
It is vertical because 4 + 4 (adding both X-axis, totalling 8) is smaller than 9 + 2 (adding both Y-axis, totalling 11), so the Y-axis, which is vertical, is bigger.
Answer:
see explanation
Step-by-step explanation:
(a)
0 < 5 ⇒ f(0) = x + 4 = 0 + 4 = 4
f(0) = 4
(b)
5 ≤ 6 < 7 ⇒ f(6) = 8
Answer:
y=-x^2
Step-by-step explanation:
given that y = x^2 is the function.
For equivalent to -y, we can multiply this equation both the sides by -1
We get -y = -x^2
Hence option G is right.
Also y =x^2 is a parabola with vertex at origin open up.
Hence if F is selected we get -y =(-x)^2 = x^2, this will make the parabola open down and hence this option is wrong.
H: -y=-x is wrong because this represents a line but we had original equation as that of a parabola
J) -y = x^(-2) means x^2y =-1
This implies that rate of change of y = 2/x^3 but rate of change of y has to equal 2x since y = x^2 is original. Hence only option G is right.
Answer:
{21, 22, 23, 24}
Step-by-step explanation:
m>20 means that m is greater or more than 20, therefore 21, 22, 23, and 24 are all greater than 20 so that is the answer.
Answer:
Step-by-step explanation:
4(x^2 = 6x + 9)
4(x + 3)(x + 3)
