Answer:
C = 6 + 2.5g
Step-by-step explanation:
A local lawn service charges $6.00 per cut plus $2.50 per gallon of gas used.
If in a cut g gallons of gas is used then, the cost for gas used will be $2.5g and there is a fixed charge of $6.00 per cut.
Therefore, in total the cost per cut becomes 6 + 2.5g and if we represent the total cost as C, then we can write
C = 6 + 2.5g. (Answer)
I think the answer's 7/8. If you convert 1/4 to 2/8 and add them together, you add 5/8 and 2/8 to get 7/8.
You just have to plug in each thing:
So f(0):
3(0)^2 - 4 = -4
so its not A
f(-2) and f(2):
3(-2)^2 - 4
3(2)^2 -4
now we don't even have to calculate these, anything to the power of an even number is a positive number so -2^2 and 2^2 both equal 4
B is correct, so you can do the others if you want to check, but if B is true the others shouldn't be true.
The y-intercept is (0,7) and the x-intercept is (-2,0).
