Answer:
The set of output values are (1,3,11,17) as Range
Step-by-step explanation:
Given function is f(x)=2x-3 and domain is (-1,0,4,7)
Function is given that taking set of input values from domain and give out set of output values.
For x=(-1)
f(x)=2x-3
f(-1)=2(-1)+3=(-2)+3=1
For x=0
f(x)=2x-3
f(0)=2(0)+3=3
For x=4
f(x)=2x-3
f(4)=2(4)+3=-8+3=11
For x=7
f(x)=2x-3
f(7)=2(7)+3=14+3=17
Thus,
The set of output values are (1,3,11,17) as Range

54 units²</h2><h2 />
This is a compound shape. You can split it into x shapes. See Attachment
Area of a Rectangle = L × B
L = 7
B = 6
7 × 6 = 42
<h3>42 units²</h3>
Area of a Triangle = 1/2BH
B = 6
H = 1
1/2 × 6 × 1 = 3
<h3>3 units²</h3>
Area of a Triangle = 1/2BH
B = 3
H = 2
1/2 × 3 × 2 = 3
<h3>3 units²</h3>
Area of a Triangle = 1/2BH
B = 2
H = 6
1/2 × 2 × 6 = 6
<h3>6 units²</h3><h3 /><h3>42 + 6 + 3 + 3 = 54</h3>
F(x) = 9x² - 54x - 19 = 9x² - 57x + 3x - 19 = 3x(3x - 19) + 1(3x - 19)
= (3x - 19)(3x + 1)
f(x) = 0 if 3x - 19 =0 or 3x + 1 = 0
3x = 19 or 3x = -1
x = 19/3 or x = -1/3
