Answer:
No, it is not a function.
Step-by-step explanation:
A function graph are graphs where the lines do not connect. Since the shape is a circle, many lines in the graph are connecting.
C i believe because 180 is the overall degree and 50+28=78 and 180-78=102
<span>y = tan^−1(x2/4)</span>
tan(y) = x2/4
sec2(y) = x/2
y′ = xcos^2(y)/2
<span>cos^2(y) = <span>16x2+16</span></span>
<span>y′ = <span>8x/(<span>x2+16)
let u be x2+16
du is 2x dx
dy = 4 du / u
y = 4 ln (</span></span></span>x2 <span>+ 16)
y at x =0 = </span> 4 ln (<span>16) = 11.09</span>
