Answer:
domain: {x | x is a real number}
range: {y l y> -8}
Step-by-step explanation:
f(x) = 4x² – 8 is a parabola, a U shape.
Since the stretch factor, 4, is positive, it opens up, there it will have a minimum value, the lowest point in the parabola.
y > -8 because the minimum is -8.
Parabolas do not have restricted "x" values. "4" does not restrict x because it is the stretch factor, which determines how wide the parabola is.
Quadratic standard form:
f(x) = ax² + bx + c
"a" represents how wide the graph is. If it's negative it opens down, if it's positive it opens up.
"b", if written, tells you it is not centred on the y-axis. It is not written, so the vertex is on the y-axis.
"c" is the y-intercept. In this case, since b = 0, it is also the minimum value.

Answer:
35 degrees
Step-by-step explanation:
Degrees in a triangle: 180
Assume Angle C = 90 degrees
180-55-90 = 35 degrees
Answer:
#3×|x-9|=0
|x-9|=0
X-9=0
X=9
# |2x-9|-4=2
|2x-9|=2+4
|2x-9|=6
2x-9=6
2x=9=-6
X=15/2
X=3/2
1 to x power =3/2 or
2 to x power =15/2
