Fill in the given values in
... y = (amplitude)×cos(2π(x + (horizontal offset to the left))/(period)) + (vertical shift)
... y = 4×cos(2(x+pi/2)) +3
_____
Note that the period is π and the horizontal offset is π/2, half a period. This has the effect of turning the waveform upside down.
Answer:
C. 7
Step-by-step explanation:
We have been given graphs of two exponential functions, f and g.
We can see that our parent function f(x) is translated k units to get function g(x).
The rules for translation are mentioned below.
Horizontal shifting:
= Graph shifted to right by a units.
= Graph shifted to left by a units.
Vertical shifting:
= Graph shifted upwards by a units.
= Graph shifted downwards by a units.
Upon comparing our given graph with transformation rules we can see that our function f(x) is translated k units upward to get function g(x).
Now let us find the value of k from our given graph.
We can see that initial value (y-intercept) of f(x) is -4 and initial value of g(x) is 3. Difference between y-intercepts of both functions is 7.
Our parent function f(x) is shifted 7 units upwards to get new function g(x), therefore the value of k is 7 and option C is the correct choice.
X = 57. Use the rules for inscribed angles. If that exterior angle is 123, then its supplement is 57. That 57 degree inscribed angle has an intercepted arc that is also the same arc that angle x intercepts. So x has the same measure as the other inscribed angle. Your answer is B.
