Question

What is the value of F(x) = 4x+9
When x= 5

Answer 1

`F(x)=29`

Explanation:

Given function:

`F(x) = 4x+9`

Find F(x) at ,
`x= 5`

The value of 'x' is given for which we have to find the value of F(x)

Putting the given 'x' in the function equation

`F(x) = 4x+9\\\\ F(x) = 4(5)+9\\\\ F(x) = 20+9\\\\ F(x) = 29`

So ,
`F(x)=29` at
`x=5`

Answer 2

f(5) = 29

Explanation:

Step 1: Identify the function

f(x) = 4x + 9

Step 2: Let x equal 5 in the function

f(5) = 4(5) + 9

Step 3: Multiply

f(5) = 20 + 9

Step 4: Add

f(5) = 29

Answer: 29
