With inverse functions you just swap 'x' and 'y' and solve for 'y'.

Swap 'x' and 'y':

Add 7 to both sides:

Take the square root of both sides:
 
 
        
        
        
the solutions to a general quadratic equation is
X=-b±√b²-4ac/2a  ,, When ax²+bx+c=0
the discriminant is the expression under the radical b²−4ac
Part A:
discriminant is (-16)² - 4(9)(60) = -1904
there are two complex solutions  
Part B:  
4x² + 8x − 5 = 0
4x² + 10x -2x - 5=0
2x ( 2x + 5) - 1(2 x + 5) =0  
(2x + 5)(2x-1) = 0
       /                     \
     /                          \
2x+5 = 0                 2x-1 =0    
x = -5/2                     x = 1/2
 
        
             
        
        
        
Answer:
y=-8x-2
Step-by-step explanation:
The formula for slope is y2-y1/x2-x1. Take coordinate (0,-2), which is the y-intercept. We'll call that (y2,x2). Coordinate (8,-3) is (y1,x1). Put that into the formula you get, 0-8/-2-(-3). You get -8/1 which is negative 8. We now have the slope. Slope intercept form equation is y=mx+b. M is slope, so we put our slope in the equation and get, y=-8x+b. B is the y-intercept which is given. So we know that the equation to this line in slope-intercept form is y=-8x-2.

First of all there isn't any graphs shown in here but i will try to show u how to work it out according to the given data.
<span>

where (x1,y1) and (x2,y2) are two points by which the line passes through.
so;
