Question

Given the function f(x)=3x^+5x-8 & g(x)2x^2-9

5. find f(2) and g(2)
6.e(x)=f(x)-g(x),find e(2)'

Answer 1

f(x) = 3x² + 5x - 8 g(x) = 2x² - 9

5.
f(2) = 3(2²) + 5(2) - 8 g(2) = 2(2²) - 9

f(2) = 3(4) + 10 - 8 g(2) = 2(4) - 9

f(2) = 12 + 10 - 8 g(2) = 8 - 9

f(2) = 14 g(2) = -1

i didn't understand the second part but i hope you understand, God bless!
