Answer:
x intercept =
Step-by-step explanation:
i show how i did it on the picture! :)
and for future reference, if you need to figure out the y-intercept, just do what i did but except cover up the x! :)
Answer:
y=2/3x-2
Step-by-step explanation:
y-y1=m(x-x1)
y-(-6)=2/3(x-(-6))
y+6=2/3(x+6)
y=2/3x+12/3-6
y=2/3x+4-6
y=2/3x-2
Answer:
5280 feet
Step-by-step explanation:
one loop is 1 fourth of a mile
she walked 4 times, making it a full mile.
So, she walked 5,280 feet in total
0+12, 11+1, 4x3, 6x2, etc.
Answer:
g(x) = x+1
Step-by-step explanation:
Informally, you can see that the function h(x) takes the root of a value that is 1 more than the value under the same radical in f(x). This suggests that adding 1 to x in f(x) will give you h(x). That is, ...
h(x) = f(x+1) = f(g(x))
so
g(x) = x+1
_____
More formally, you can apply the inverse of the function f(x) to the equation ...
h(x) = f(g(x))
f^-1(h(x)) = f^-1(f(g(x))) . . . inverse function applied
f^-1(h(x)) = g(x) . . . . . . . . . simplified
Now f^-1(x) can be found by solving for y in ...
x = f(y)
x = ∛(y+2) . . . . . . . . . definition of f(y)
x^3 = y+2 . . . . . . . . . cube both sides
x^3 -2 = y = f^-1(x) . . . subtract 2 from both sides
So, f^-1(h(x)) is ...
f^-1(h(x)) = g(x) = (∛(x+3))^3 -2 = x+3 -2
g(x) = x+1
