Explanation:
The function is
To graph the function, let us find the x and y intercepts.
To find x-intercept, let us substitute y=0 in the function
Thus, the x-intercept is
To find the y-intercept, let us substitute x=0, we get,
Thus, the y-intercept is
The graph has no asymptotes.
To plot the points in the graph, we need to substitute the values for x in the function , to find the y-values.
The points are . The image of the graph and table is attached below:
Answer:
a = 7, b =
Step-by-step explanation:
Using the sine ratio in the left right triangle and the exact value
sin45° = , then
sin45° = =
=
( cross- multiply )
a × = 7
( divide both sides by
)
a = 7
--------------------------------------------------------
Using the tangent ratio in the right triangle on the right and the exact value
tan60° = , then
tan60° = =
=
=
( multiply both sides by b )
b × = 7 ( divide both sides by
)
b = ×
=
