What you said doesn't even make sense.
I'll assume you said f(x) = -5x^2 + 4.
This is an even function.
f(-x) = f(x)
Answer:

Step-by-step explanation:
The surface area of a cylinder is given as;

where r = radius
h = height
The cylinder has a height of 32 feet and a diameter of 40 feet. This means that the radius is:
40 / 2 = 20 feet
The surface area is therefore:

The surface area of the cylinder is
.
M = mass
So E = mc^2 is
Kinetic energy = mass * speed of light^2
Answer:
x=7,-17/3
Step-by-step explanation:
First you solve the inequality. Add the variables that can be added together. That would be -3 + 1=2. Now the equation is 2 + x<6. After you change the 2 into a negative and put it under the 6 and subtract. that is 3. 3 is the number you put on the number line. When you fine and plot three you make a dot above it. You fill in the dot since the less then sign has a line beneath it. Then you draw a line from the dot to the end of the number line from the direction the sign is facing. It’s a less then sign, so you would draw the line to the left.
