Answer:
3
Step-by-step explanation:
g(x) = x² + 2x+4
h(x) = -3x+2
(g*h)(1) is the same as
g(h(1)) , next solve for h(1) first by substituting in h(x), x with 1
g( h( x= 1)) = g( -3*1 +2) = g( -1) so substitute in g(x) , x with -1
g(x= -1) = (-1)² +2(-1) +4 =1-2+4 =3
Answer:
y=90 when x=4
Step-by-step explanation:
We are given that

When x=8 and y=250
We have to find the value of y when x=4

Where k= Proportionality constant
Substitute the values




Now, substitute x=4 and k=5/2
Then, we get
