Answer:
Zeros
x = -3 point (-3 ,0)
x = 3 point (3 ,0)
Step-by-step explanation:
Using a graphing calculator, we can easily check the intercepts of the equation
y = -x^2 +9
Answer:
C: 
Step-by-step explanation:
Amplitude is changed by multiplying the entire trig function by a number, by default the amplitude is 1, so multiplying by 6 is necessary; eliminate A and B
Horizontal shift is going through the x axis, so it must be subtracted from the x value. This is only seen in choice C of the remaining answers.
Calculating the period isn't necessary because we already found the right answer but in case you need it in the future; the period is by default 2pi, to get to pi/4, it had to be 8 times smaller, so multiplying x and translations on x by 8 will get you the correct period.
Add up the two acres 60 3/4
then multiply by 4/5 and you get 48.6
that should be your answer.
Answer:
1. 5b^2-b-2 (so option 3)
2. 4x-1 (so option 2)
Step-by-step explanation:
For the first one you need to just simplify the expression
For the second one you need to combine like terms
