Helps me solve 2 and 4 please

g(-4)= -8 and f(9)= 44

Step-by-step explanation:

g(x)=2x^2+10x

g(-4)=2(-4)^2+10(-4)

g(-4)=2(16)-40

g(-4)= -8

f(x)=l1-5xl

f(9)= l1-5(9)l

f(9)= l1-45l

f(9)= l-44l

f(9)= 44

16.3.

Step-by-step explanation:

i just took the test.

It's asking us to find the input value x such that f(x) = g(x). So let's look at the columns f(x) and g(x). We can see that both f(x) and g(x) have the value of 3. The x-value at which f(x) = g(x) = 3 is x = –1.  

Thus the answer is x = –1.
