Answer:
f(20) = 168
Step-by-step explanation:
To find the 20th term, substitute n = 20 into f(n) , that is
f(20) = 9(20) - 12 = 180 - 12 = 168
It might be:
y=2x+6+2x-8 (times out the brackets)
y=4x-2
y intercept=-2
The graph of a quadratic function y = ax² is a VERTICAL parabola open upward or downward depending whether a (the coefficient of x) is positive or negative
The graph y² = ax or y = √ax is a HORIZONTAL parabola open to the right or to the left depending whether a (the coefficient of x) is positive or negative
