Question

Find each value if h(x) = x^2 +3x if x=(2x)

Answer 1

Answer: 4x^2 + 6x.

Explanation:

To find the value of h(x) when x=2x, we can substitute 2x in place of x in the given function h(x) = x^2 + 3x.

Step 1: Substitute 2x in place of x in the function:

h(2x) = (2x)^2 + 3(2x)

Step 2: Simplify the expression:

h(2x) = 4x^2 + 6x

So, the value of h(x) when x=2x is h(2x) = 4x^2 + 6x.

This means that if you substitute 2x in place of x in the function h(x) = x^2 + 3x, you will get the expression 4x^2 + 6x.

Hope this helps.

Answer 2

`\sf h(2x) = 4x^2 + 6x`

Explanation:

Given:

`\sf h(x) = x^2 + 3x`

To find
`\sf h(2x)`, replace
`\sf x` with
`\sf 2x` in the expression:

`\sf h(2x) = (2x)^2 + 3(2x)`

Simplify the expression:

`\sf h(2x) = 4x^2 + 6x`

So,
`\sf h(2x)` is equal to
`\sf 4x^2 + 6x`.
