Step-by-step explanation:
There you go............
Answer:
3.13
Step-by-step explanation:
Because the 4 is in the hundreds place. The rule for the number would be less than five so round down. 4-1=3.
Ok so: the graph of a function intersects the x-axis will be the roots of f(x) = 0. Because the coordinates of the point where it intersects the xaxis will be (x, 0). y will be 0. What you need to do is add 0 wherever x is for eample: <span>when multiplying 3 and 0 you get 0 then subtract 2 and y would equal negative 2. I hope this helps you</span>

x + y = -54
2 + y = -54
- 2 - 2
y = -56
(x, y) = (2, -56)
or
x + y = -54
-56 + y = -54
+ 56 + 56
y = 2
(x, y) = (-56, 2)
The two numbers that multiply to -12 and add up to -54 are -56 and 2.
Answer:
f(x) = (8/3)^x
Step-by-step explanation:
Since f increasing, the base value must be greater than 1.
8/3 is the only base value greater than 1.
The base (3/8) would be a decreasing graph because it is less than 1.
The base (-3/8) would result in a wavering graphing passing the x-axis many times. (Because whether the result is negative depends on if x is odd or even.)
in (8/3)^(-x), it is the same as (3/8)^x by applying the negative exponent rule a^(-x) = 1/(a^x).
