arlik [135]

Divide by 7.

... |-7x -3| = 3

Unfold to two equations.

... -3 = -7x -3 . . . . . the content of the absolute value is negative

... 0 = -7x . . . . . . . . add 3

... 0 = x . . . . . . . . . . divide by -7

and

... 3 = -7x -3 . . . . . . the content of the absolute value is positive

... 6 = -7x . . . . . . . . add 3

... -6/7 = x . . . . . . . . divide by -7

The solutions are ...

... x = -6/7 or x = 0

_____

Many graphing programs will happily tell you the locations of x- and y-intercepts, so it is convenient to rewrite the equation so its value is zero at the solution points. We can do that by subtracting the right side constant to get ...

Which of the quadratic functions has the narrowest graph? y = –2x2 y=-1/2x^2 y = –4x2 y=1/7x^2
vovikov84 [41]
Look at the coefficient of x², ignore the positive or negative sign. The larger the coefficient, the narrower the graph. 
in this case, the coefficients are -2, -1/2, -4, and 1/7
ignore the positive or negative sign, 4 is the largest number, so y=-4x² is the narrowest.

Note: the positive/negative sign tells you whether the graph opens upward or downward. It doesn't determine the width of the graph.
