Question

If f(x)= 6x+7, determine the value of f(-3)

Answer 1

For this you simplify plug in or substitute-3 wherever you see an x in the equation and then simplify.

f(-3)=6(-3)+7
f(-3)=-18+7
f(-3)= - 11

Answer 2

To evaluate a function at a specific x value simply means to substitute that particular value in place of every occurrence of the variable x.

So, starting from
`f(x) = 6x+7`, we have

`f(-3) = 6\cdot(-3)+7 = -18+7 = -11`
