Question

Find the value of f(3) for the function f(x)=4x+10

Answer 1

f(3) = 22

Explanation:

Substitute x = 3 into f(x) , that is

f(3) = 4(3) + 10 = 12 + 10 = 22

Answer 2

`\\ \sf\bull\longmapsto f(x)=4x+10`

`\\ \sf\bull\longmapsto f(3)`

`\\ \sf\bull\longmapsto 4(3)+10`

`\\ \sf\bull\longmapsto 12+10`

`\\ \sf\bull\longmapsto 22`
