the x-intercept is the point where the line touches the x-axis. The x-intercept is (4,0)
the y-intercept is the point where the line touches the y-axis. The y-intercept is (0,-2)
I can not see the image you provided .
H(25) = sqrt25 = 5
g(5) = 5 - 3 = 2
answer is 2
Well divide them. 2/3=0.666 repeated. So use a bar over the top of the third six.
