<u>Given function:</u>
- y = -2(x - 3)² + 4
<em>The graph is attached and the axis of symmetry and all the required points plotted </em>
a) Axis of symmetry:
- x = 3
b) It has no minimum as the leading coefficient is negative.
- Maximum value is at vertex- the point (3, 4).
- Maximum value is y = 4
c) and d) x - and y - intercepts already given in the question
e) Domain is all real numbers. x = ( -∞, +∞ )
Range is y = ( - ∞, 4]
=> The answer is <u>2</u><u>.</u>
Answer:
The pre-tax price of "smart fabric" warm-ups is $745 .
Step-by-step explanation:
Let us assume that the pre-tax price of the "smart fabric" warm-ups be x .
As given
arold paid 5% in sales tax on his new "smart fabric" warm-ups.
if harnold paid 37.25 in sales tax on the warm ups .
5% is written in the decimal form .
= 0.05
Equations becomes
0.05 × x = 37.25
0.05x = 37.25
x = $745
Therefore the pre-tax price of "smart fabric" warm-ups is $745 .
