Answer:
f(0)=1
Step-by-step explanation:
The question asks us to find f(0). We want to find what f(x), or y is, when x is equal to 0.
f(x)=3^x
Therefore, we can substitute 0 in for x.
f(0)=3^0
Evaluate the exponent, 3^0.
Any number raised to the power of zero is equal to 1.
f(0)=1
The factored form of the expression is
The expression x^2 + 9 has no real roots hence cannot be factored
Quadratic equations are equations with a degree of 2.
Given the quadratic function
For the function
Using the difference of two squares:
For the expression x^2 + 9
The expression x^2 + 9 has no real roots hence cannot be factored

sorry if im wrong.
Answer:
$52
Step-by-step explanation:
Using the equation
y=mx+c
82=7x+c
122=11x+c
11x-7x=122-82
4x=40
x=10
To get c
82=7(10)+c
82-70=c
c=12
For 4 lessons
y=10(4)+12=52
