Answer:
Graph will open same way and is narrower.
Step-by-step explanation
If: f(x)= x^4
f(-2x)= (-2x)^4
Negative sign usually flips the graph and make it open to the opposite direction. In this case since the function is to the 4th degree and the negative sign is included. The negative is basically ignored.
The term in front of x (a) determines how wide the graph opens. The bigger the a value the faster the slope increases so the narrower the graph opens.
Think if the slope is 4 vs 1/4.
Hope this helps
Answer:
x>60 or x=60
Step-by-step explanation:
The must be 60 or more inches.
For some value of z, the value of the cumulative standardized normal distribution is 0.8340. the value of z is
Answer: We are required to find the value of z corresponding to probability 0.8340.
i.e., 
We can find the value of z using the standard normal table.
Using the standard normal table, we have:
Therefore, for the value of z = 0.97, cumulative standardized normal distribution is 0.8340
Attached here standard normal table for your reference.
Answer:
2x - 3
x - 9
Step-by-step explanation:
The root of a problem is the x value that makes the equation equal to zero.
If the factored form of the equation is (2x-3)(x-9) that means if either 2x - 3 or x - 9 is equal to zero, the entire equation will equal zero, because zero times any number is equal to zero.
Therefore you must solve for (2x-3)=0 and (x-9)=0
