Question

Can someone answer these??

Answer 1

Use the substitution method

Answers :

g(x)= -3x+1

a. g(10)= -3(10)+1

Mutiply first = -30

-30+1= -29

g(10)= -29

b. g(-2)= -3(-2)+1

Negative sign and negative sign = positive sign

-3(-2)= 6

6+1= 7

g(-2)= 7

a.

f(x)=x^2+7

f(3)= 3^ 2+7

3*3 because of the exponent. 3*3= 9

9+7= 16

f(3)= 16

d.

f(a)= a^2+7

a*a= a^2

a^2+7

f(a)= a^2+7
