Find the range of the function f(x)=4x-1 for the domain {-1 0 1 2 3}
{-5,-3,0,7,11}
{-5,-4,-3,-2,-1}
{-11,-7,-3,1,5}
{-5,-1,3,7,11}

  {-5, -1, 3, 7, 11}

Step-by-step explanation:

The function tells you that a value in the domain is multiplied by 4 and 1 subtracted from the result. Here, the given domain is {-1, 0, 1, 2, 3}.

Multiplying each value of the given domain by 4, we get ...

  {-4, 0, 4, 8, 12}

Then subtracting 1 gives ...

  {-5, -1, 3, 7, 11} . . . . . matches the last choice

Hello!

To find the x-intercept given the equation of a line, we substitute y for 0 and solve for x.

0=4x²-9

We add 9 to both sides.

9=4x²

We find the square root of both sides.

3=4x

We divide both sides by 4.

x=3/4

Therefore, our x-intercept is 3/4.

I hope this helps!
