What does how many mean a math problem is it división, multiply, or subtract, add

Given the function:

f(x) = the quantity of x squared plus 3x minus 4 , all over x plus 4

i,e

or

or

or

⇒y= f(x) = x -1                 ......[1]

Find the x-intercepts and y-intercepts for the equation [1] ;

y-intercepts defined as the graph crosses the y-axis;

substitute x =0 to solve for y;

y = 0-1 = -1

y = -1

x-intercepts defined as the graph crosses the x-axis;

substitute y =0 to solve for x;

0 = x-1

or

x = 1

Plot these points (0 , -1) and (1, 0) on the graph for the given function as shown below.
