Answer:
Step-by-step explanation:
1 × a = a
a² = a*a ; a³ = a*a*a .....
<em>(1).</em>
(a).
(b). =
(c).
<em>(2).</em>
(e). =
=
(f). =
×
=
<em>(3).</em>
x² = 30² + 16² = 900 + 256 = 1156 = 34² ⇒ <em>x = 34 units</em>
The X-intercepts: (1,0),(-7,0)
Axis of symmetry: x= - 3
The vertex: (-3, -8)
The Y-intercept: (0, -7/2)
Concave up or down: concave up
