Answer:
no solution
Step-by-step explanation:
The given data are:
A function that:
The domain is the set of all real numbers
One x-intercept
The amplitude is 4
The y-intercept is (0,0)
From the choices, the functions containing "cosine" can be eliminated since the described function passes through (0,0). So, we are left with two choices:
y = -4sin (x) and y = 4sin (x)
Given the amplitude of 4, the answer must be y = 4 sin(x)
Answer:
Read explanation and apply it
Step-by-step explanation:
The vertex form of a quadratic equation is 
The general form of a quadratic equation is 
The factored form of a quadratic equation is 
The one which reveals the zeros of f(x) without needing to alter the equation is the factored form .
When f(x)=0, we have 
The values of x are 
and 
.
I hope this guides you to choose the correct answer.
This is a linear function y=mx + b
If x = 0 then y=b, if A is the point where y intercepts y-axis, the coordinates of
A(0,b)
If you want to shift the graph up by 2 units, then you have to add 2 units to b
In our case original b=7, =so to shift it up, b becomes 7+2=9
and the new function will be y=2x + 9
