Answer:
x = , y = 2
Step-by-step explanation:
using the tangent ratio and the exact value tan45° = 1 , then
tan45° = =
= 1 , then
x =
----------------------------------
using the cosine ratio in the right triangle and the exact value
cos45° = , then
cos45° = =
=
( cross- multiply )
y = ×
=
= 2
The correct option A: graph A, shows the logarithmic function;
f(x) = log₃x + 1
<h3>Explain the term logarithmic function?</h3>f(x) = log₃x + 1
f(1) = log₃1 + 1
f(1) = 0 + 1
f(1) = 1
(1, 1)
f(3) = log₃3 + 1
f(3) = 1 + 1
f(3) = 2
(3, 2)
Thus, the graph must contain the points (1, 1), (3, 2).
Therefore, graph A define the given logarithmic function;
f(x) = log₃x + 1.
