Your choices are correct.
1. adding -3 to the function shifts its graph downward by 3 units.
2. 7^(2x) = (7^2)^x = 49^x
3. f(0) = -6; g(0) = -3, f(0) = 2×g(0)
Answer: 1/7
Step-by-step explanation:
solve for y
For this case we have the number in exponential notation:

We observe that the exponent of the exponential notation is positive.
Therefore, to express the number as a whole number, we must move the comma 6 spaces to the right.
We have then:

Answer:
this distance written as a whole number is:
miles
Answer: x=18
Step-by-step explanation:
X/3=6
We want to get x alone so we multiply both sides by 3
X=18
(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.
