Answer:
C:-217
Step-by-step explanation:
f(-2)=0.5*(-2)^2+9.5*(-2)-200
=2-19-200
=-217
Answer:
g(f(x))=x^2 + 14x + 48
Step-by-step explanation:
you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.
Since 20 min is 1/3 of a mile 20 min*3=1 hour. then u multiply 2/5 by 3 to get 6/5.
Answer:
I don't think that there is two same results. sorry I couldn't help
Step-by-step explanation:
for I the answer should be 10 if you replaced each x by 2. f(2) = 3(2) + 4
and for II it will be f-1(4) = 3-1(4) - 4 /5 the answer will be -1.
for III it should be y = 8 or 4
Answer:

Step-by-step explanation:
Let's assign variables to the various variables in the equation.
Let's say domain will be the variable
.
Let's say range will be the variable
.
Range is equal to two-thirds of the domain, so domain times two-thirds will equal the range.

This should also be reduced by three, which is just another way of saying subtract.
