What is true of the function g(x)=-2x^2+5?

Mathematics

mart [117]3 years ago

Answer:

C) The variable x represents the independent variable.

Step-by-step explanation:

The given function is g(x)=-2x^2+5.

g(x) is NOT the multiplication of g and x because g is a function of x.

x is the input of the function.

-2x^2+5 is the output of the function.

The variable x is called the independent variable because we plug in values of x to find g.

The variable g represents the output of the function NOT the input.

The correct choice is C

Answer: B

Step-by-step explanation:

Domain is x values

Range is y values

Domain you look from left to right. You can see it starts at -3, and it goes all the way to 2. NOT 4 BUT 2!! Since we are looking at the X.

Range.. WE ARE LOOKING AT THE LOWEST POINT!! LOWEST POINT FIRST!1 I cannot stress enough. The lowest y-value is -2, and it's maximum point is 4!

REMEMBER:

DOMAIN = X LEFT TO RIGHT

RANGE= Y LOWEST POINT TO HIGHEST

The grocery store is having a sale on frozen vegetables. 4 bags are being sold for 11.96. At this rate what is the cost of 1 bag
Grace [21]

Answer: $2.99 (I’m assuming this is money)

Step-by-step explanation: To find the answer you first divide 11.96 by 4. That is because If the there are 4 bags for a total of 11.96 the cost of one bag will go into the total four times.

So 11.96 divided by 4 is 2.99. That means that 2.99 is the cost of one bag because 2.99 multiplied by 4 is the total.
