Substract the following :(4x^3+6x+9)-(-15x^2+7x-2)

1 answer:

7 0

To solve this, we need to rearrange to get like terms by each other. Remember to distribute the negative.

$4x^3+6x+9+15x^2-7x+2

4x^3+15x^2+6x-7x+9+2

4x^3+15x^2-x+11$

What is the range of f(x)= -3^x+4

V125BC [204]

Answer:

A. The set of all real numbers less than 4

Step-by-step explanation:

The range of the parent function $y=3^x$ is $y\in (0,\infty)$

The graph of the function $y=-3^x$ is reflected across the x-axis graph of the parent function, so the range of the function $y=-3^x$ is $(-\infty,0)$

The graph of the function $y=-3^x+4$ is translated 4 units up graph of the function $y=-3^x$ , so the range of the function $y=-3^x+4$ is $(-\infty,4)$ or the set of all real numbers less than 4.
