Answer:
f(3) = 9
Step-by-step explanation:
Wherever you see an x on the right, put a 3 in for that x
f(x) = 2x^2 + x - 12
f(3) = 2*(3)^2 + 3 - 12
f(3) = 2*9 + 3 - 12
f(3) = 18 + 3 - 12
f(3) = 9
First substract $130.00 from $1009.88 like this:

Then substract $6.19 we get:

$873.69 is the remaining amount in <span>Jane hitman's account. </span>
the standard form of that graph is ax squared +bx+c
