For -(4)^7
the - is not affected by the power of 7
For (-4)to the power of7 is the same as -4 to the power of 7
It is because 7 is an odd number,the - will not change .Therefore
(-4)^7= -(4)^7
But keep in mind that if the power is an even number , the - will change to + when the situation is (-4)
For example,(-4)^4=(4)^4
I am not good at English if there is any things that you feel confused you may ask
-1^3-5(-1)^2+2(-1)+8
-1-5-2+8
-6-2+8
-8+8=0
[0, inf)
The least y-value the function can have is 0 because the square of a number cannot be negative.
I’m not totally sure about the less and greater signs because I’m not sure you can graph using those signs but either way their are your line equations
