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
4 ⁽ˣ⁺⁵⁾ = 16 (x-3)
Simplify.
4x + 20 = 16x - 48
Subtract 16x from both sides, as well as subtracting 20 from both sides.
4x - 16x = -48 - 20
Add like terms.
-12x = -68
Divide both sides by -12
x = 5 2/3
