2x(2x+3)<br> Expanding brackets please
valina [46]

Answer:

54 or 15

Step-by-step explanation:

x = any number

x = 3

First solve the brackets:

2x + 3

(2x3) + 3 = 9

2x = 6

I can help you up to here because the question isn't worded properly.

If you are multiplying then it would be: 9x6 = 54

If you are adding then: 9+6 = 15

Hope this helps!

Find the inverse of each function. Is the inverse a function? f(x)=x⁷
Luda [366]

The inverse of the function x^7 is x^-7 and it is also a function.

An inverse function or an anti function is defined as a function, which can reverse into another function.

A standard method to find inverse of a function is to set y=f(x)

let y= f(x)=x^7

thus

\sqrt[7]{y}=x

thus f^{-1}(y)=\sqrt[7]{y}

thus f^{-1} (x)=\sqrt[7]{x}

(To verify this if a function is inverse or not we are required to check for the identity)

f(f^{-1}(x))=f^{-1}(f(x))=x

Therefore, The inverse of the function x^7 is x^-7 and it is also a function.

Consider the quadratic function f(y) = 8y2 – 7y + 6. What is the constant of the function?
Over [174]
The constant is 6. A constant is just the number on its own. Quadratics follow the form f(x) = ax^2+bx+c. The c is the constant.
