Hello,
sin (30°)= cos (60°)=1/2 (complementary angles)
sin D= cos E
Answer C
F(x)=x
Domain: 1 2 3 4 5 6
Range: 1 2 3 4 5 6
F(x)=2x
Domain: 1 2 3 4
Range: 0 2 4 6
We need (x-h)^2 + (y-k)^2 = r^2
h = 4, k = 0 and r = 2/3
Take it from here.
We have the function and we want to find a function that has the same y-intercept than the previous function.
First, let's find the y-intercept by subtituting 0 for 'x'.
Now that we found that y-intercept =-3, any lineal function of the type: will have the same y-intercept. Where 'a' can take all the real values.
Also, any quadratic function of the type: will have the same y-intercept. Where 'a' and 'b' can take all the real values.
