Question

Need help in math and explain to me step by step

Answer 1

`\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]`

Explanation:

Given

`y = 4x - 1`

Required

Create a function table for inputs -2, 0, 2 and 4

When x = -2

`y = 4*-2 - 1 = -9`

When x = 0

`y = 4*0 - 1 = -1`

When x = 2

`y = 4*2 - 1 = 7`

When x = 4

`y = 4*4 - 1 = 15`

So, the table is:

`\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]`
