Answer: F (x) = 5x^2 + 10
The answer is 1 .........................................................................................................................................................................................................................................
Start by distributing
30x - 300 = 15x
add 300 to both sides
30x = 300 + 15x
subtract 15x from both sides
15x = 300
divide both side by 15
x = 20
The pattern is minus 6 and the slope ypu can find by 4 minus 10 over -4-(-2) then simplify
