The answer is true.
Method 1:
The given function is a cubic function. And inverse of a cubic function is also a function.
Method 2:
Since the function is one-to-one function i.e it passes the horizontal line test, its function will pass the vertical line test which is a test if a relation is a function or not.
So, yes the inverse of G(x) will be a function.
Answer:
The answer for standard deviation would be:
4.382
Answer:
H0: p = 0.078
Ha: p ≠ 0.078
Step-by-step explanation:
The researchers say that the rate is about 7.8%, or 0.078 as a decimal. That makes that the null hypothesis because using "is" in math is the same as saying "equals" and the null hypothesis always has the statement of equality in it. The reason there is a not equals to sign in the alternate is for this reason as well. The researchers say it is about that amount, not more or less than that amount. So it makes this a 2 tailed test. If the amount is significantly higher or lower, then we might have to reject the null hypothesis depending on the outcome of the test.
Answer:
Y=2x+0
Step-by-step explanation:
First you have to find the slope of the graph or the rise over run, which in this case is 2
Then you have to find the y intercept, which is zeroSo the rule for thos graph is y=2x+0.
To double check our work take a random point on x axis. I chose the point 1,2
fill in the formula and you should get 2(1)+0=2 and therefore this Formula is correct
Answer:
-18
Step-by-step explanation:
3(-4) - 6
-12 - 6 = -18
