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 [tex] f(x) = 6x+7 [/tex], we have

[tex] f(-3) = 6\cdot(-3)+7 = -18+7 = -11 [/tex]

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
