F(x) = 2x2 + 9x
Find f(10)

290

Step-by-step explanation:

since f(x)=2x^2 +9x

and we have to find f(10)

then we put the value of x as 10 and we get

f(10)=2(10)^2 +9(10)

=2(100)+90

=290

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
