Step-by-step explanation:
A graphing calculator can help you do this.
__
The function crosses the y-axis where x=0.
g(0) = -5^0 +5 = -1 +5
g(0) = 4
The function crosses the x-axis where g(x) = 0
0 = -5^x +5
5^x = 5 = 5^1
x = 1
g(1) = 0
The points of interest are (0, 4) and (1, 0).
If the questions are asking where the two equations meet the answer is (1,1)
Answer: B. All real numbers

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.
