The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
<h3>What are exponential functions?</h3>
When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function.
here usual form is specified below. They are written in several such equivalent forms.
The equation of the function is given as:

Set x = 0, 1, 2 and 3

This means that the graph of the function f(x) = 3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20).

We can often solve inequalities by adding or subtracting a number from both sides
Answer:
1)
32x^2 - 28x - 15
2)
30x^2 + 54x - 12
Step-by-step explanation:
1.
(8x+3)(4x-5)
Using FOIL
= (8x)(4x) + (8x)(-5) + (3)(4x) + (3)(-5)
= 32x^2 - 40x + 12x - 15
= 32x^2 - 28x - 15
2.
(10x-2)(3x+6)
Using FOIL
= (10x)(3x) + (10x)(6) + (-2)(3x) + (-2)(6)
= 30x^2 + 60x - 6x - 12
= 30x^2 + 54x - 12
Answer:
Step-by-step explanation:
- 20 + 2 < x/3 - 8
- 22 + 8 < x /3
- 30 < x /3
- 30*3 < x
- 90 < x
- x > 90
Correct choice is C
(4w-8)+(3w+6)=180
7w-2=180
7w=180+2
7w=182
w=26
