Answer:
,
Step-by-step explanation:
If two items or expressions are equal to the same subject then they are equal to each other,
y = 4x + 22 and y = -7x
Using the statement at the top
<em>Subtract -7x from both sides to collect the x terms</em>
<em>Minus 22 from both sides to isolate 11x</em>
<em /><em />
<em>Divide both sides by 11 to isolate x</em>
<em /><em />
<em>Substitute x = -2 into y = -7x</em>
<em /><em />
So the solution is and

Actually Welcome to the concept of expo functions.
f(x) = -8(2)^x - 12 ,
for f(0) ,here substitute x = 0
so we get as ,
==> f(0) = -8(2)^0 -12
==> f(0) = -8-12
==> f(0) = -20
hence, f(0) = -20
