This is all I got sorry if it don’t help
Well it will be a simple as grid algebra
3(2+12)+12x5
The slope-intercept form: y = mx + b
m - the slope
b - the y-intercept
y = 7x + 4
Answer: The y-intercept b = 4 ⇒ (0; 4)
Answer: Yes. (gof)(0) = -5
(gof)(0) means you will find the function of g(f(0)), which means we will find f(0) and plug that value in for x in the function g(x)
We know f(0) is -1, so we can plug -1 into the equation of g(x)
(gof)(0) = (-1) - 4
(gof)(0) = -5
