Answer:

16

Step-by-step explanation:

We have the expression:

b^2

We know that b= -4. Therefore, we can substitute -4 in for b.

(-4)^2

-4^2 is the same as multiplying 4, 2 times.

-4^2

=-4*-4

2 negative numbers multiplied together make a positive number.

= 16

Always follow the rules of BOMDAS. (If you don't know them or maybe learned differently tell me).
Firstly multiply 4(1/2) and then substract
8 - 4(1/2)
8 - 2

Find the range of y = 3/2 cos 4x - 1
motikmotik

Answer:

B. -2\frac{1}{2} \leq y \leq \frac{1}{2}

Step-by-step explanation:


The given trigonometric function is

f(x)=\frac{3}{2}cos4x-1.


The amplitude of this function is \frac{3}{2}, so under normal circumstances the range is supposed to be

-\frac{3}{2} \leq y \leq \frac{3}{2}

But the -1 is a downward vertical shift.

Therefore the normal boundaries  of the range will shift down one unit to give the range of the transformed function.


We subtract 1 from the lower boundary to get -\frac{3}{2}-1=-2\frac{1}{2}


We also subtract 1 from the upper boundary to get -frac{3}{2}-1=\frac{1}{2}


Hence the range is


-2\frac{1}{2} \leq y \leq \frac{1}{2}
