Answer:
f(x)=-1 and 15
Step-by-step explanation:
What you do is you put -2 and 2 into the x.
f(x) = -4(-2) + 7 = -1
f(x) = -4(2) + 7 = 15
f(x)=-1 and 15 are your answers.
Change the equation to y=-3x+1. this means the slope is -3, and the y intercept is 1. the line is dashed, and the area below the line is shaded.
The graph of the piecewise function includes
(1) a straight line passing through point (-3, 0) and stopping at point (0, 3) with an unshaded small circle at the end of point (0, 3) and an arrow at the other end.
(2) a shaded small circle at point (0, 5), and
(3) a straight line starting at the point (0, -1) and passing through the point (2, 3) with an unshaded small circle at the point (0, -1) and an arrow at the other end.
Answer:
A. Perpendicular
Step-by-step explanation:
Lines are perpendicular if their slopes are opposite reciprocals of each other. Opposite, meaning if positive, the other slope is negative, and if negative, the other slope is positive. Reciprocal meaning, the number is flipped upside down, turning fractions into whole numbers and vice versa.
1/9
-1/9
-9
The slopes are perpendicular
