Answer:
false
Step-by-step explanation:
860 divided by 2 is 430 NOT 480
Step-by-step explanation:
focus(p) is on the x axis= -1
vertex=(0,0)
parabola equation----- (y-h)^2 =4p(x-k)
(h, k)=(0,0)
(y-0)^2 =4(-1)(x-0)

y^2 = -4x
that is the answer
Answer: D
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
Can't really see the graph clearly but the range looks like its from 40-70 so 30 and the amplitude is half of that so 15.
To solve this problem you must appy the proccedure shown below:
1. You have the following function given in the problem above:
f(x)=e^2x
2. You can rewrite is:
y=e^2x
3. Interchange the variables, as below:
x=e^2y
3. The inverse of an exponential function is the logarithm function. Thereforem you have:
ln(x)=ln(e^2y)
ln(x)=2y
4.Then, you have:
y=ln(x)/2
Therefore, the answer is:
f^-1(x)=ln(x)/2
