Answer:
Step-by-step explanation:
-4b^2+6b-9-(7b^2-2b-5)=
-4b^2+6b-5-7b^2+2b+5=
-11b^2+8b-4
Domain - -9-9
Range is the same i think been a while since i have done this
Negative. There are - < these signs before the numbers, so that means they’re negative
Answer:
The range is { -1,3,7,11,15}
Step-by-step explanation:
The range is just the output values
f(-2) = 4(-2) +7 = -8+7 =-1
f(-1) = 4(-1) +7 = -4+7 = 3
f(0)= 4(0) +7 = 7
f(1) = 4(1) + 7 = 11
f(2) = 4(2) +7 = 8+7 = 15
