I am not going to do the work for you, since this easy with this information:
Quadratic- involving the second and no higher power of an unknown quantity or variable
Linear- Arranged in straight or almost straight line
Exponential- Increasing
Answer:
see explanation
Step-by-step explanation:
(A) Given
4(2x - 3) = 4 ( divide both sides by 4 )
2x - 3 = 1 ( add 3 to both sides )
2x = 4 ( divide both sides by 2 )
x = 2
(B)
As a check substitute x = 2 into the left side of the equation and if equal to the right side then it is the solution.
4(2(2) - 3) = 4(4 - 3) = 4(1) = 4 = right side
Hence x = 2 is the solution

(I)
f(x) = 5x+4
for f(-3)
Substitute the value of x given inside the blackets I.e -3
f(-3) = 5(-3) + 4
f(-3) = -15 + 4
f(-3) = -11
final answer for f(-3) is -11
(ii)
g(x) = -3x^3-2
for g(-4)
do the same as the above question
g(-4) = -3(-4) ^ 3-2
g(-4) = 12^1
g(-4) = 12
final answer for g(-4) is 12
Salt is a solid. S<span>olids are more dense than liquids: they have more atoms packed into the same space. The atoms are tightly packed together and stay in shape all by themselves, though they do move about on the spot.</span>
