Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4x + 3
f(-5) is x = -5
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(-5) = 4(-5) + 3
- Multiply: f(-5) = -20 + 3
- Add: f(-5) = -17
Answer:
a) 160°
b) 18 sides
Step-by-step explanation:
Interior angle = 180 - exterior
= 180 - 20 = 160°
Each angle of a regular polygon:
[(n-2)×180]/n = 160
180n - 360 = 160n
20n = 360
n = 18
Alternate approach for no. of sides:
360/n = each exterior angle
360/n = 20
n = 360/20 = 18
h(x) = -2x2 + 12x - 3?
The axis of symmetry is :
x = 3
