Answer:
Step-by-step explanation:
1) f(x) = 7 - 8x²
f(3) = 7 - 8*3²
= 7 - 8*9
= 7 - 72
f(3) = -65
2) f(a) = -5(a-2)
f(3) = -5(3 -2) = -5 * 1 = -5

4) f(m) = m(m +4)
f(3) = 3*(3+4) = 3 * 7 = 21
One of the rules of logarithms is as follows;

We can now insert the corresponding values in the question provided, as shown below;

Note that, one of the rules of exponents, states that a number when raised to the power of a negative value, is equivalent to the reciprocal of that expression. An example is shown below;

Therefore, our equation can now be re-written as follows;

However, the question requires the answer to be expressed in exponential form. Therefore,
Answer:
d)
Step-by-step explanation:
The domain are all the possible values for x. For this graph the domain will continue on forever in both the positive and negative direction, so (-∞, ∞).
The range are all possible values for y. For this graph, k affects the height of the graph. Since k affects how far up/ down you move the graph, therefore (k, ∞)
The h in the equation shows how far you move the graph to the left/right.
Honestly just use mathy way
